Harry noticed that his wife's spiritual comfort came from an unusual source. He would have expected Fred to comfort her, or maybe the Grandmum and Granddad Weasley that Harry had never met. Who did comfort Ginny Potter was a surprise.
Harry tried not to let bad days at work affect his home life, but today had gone too far. It was the anniversary of Mad-Eye Moody's death and some new recruit had chosen today of all days to talk about what a nutcase old Mad-Eye had been and how glad he was that Mad-Eye wasn't training anyone in the Auror program anymore. Harry had promptly taken the trainee into the dueling chamber and deliberately used only techniques that Moody had told him about to thoroughly crush his opponent.
However, instead of making him feel better, this made him feel worse as he realized he sounded a bit like a bully – beating people up because he didn't like what they said. He'd gone back and apologized to the trainee, though he gave him a strict lecture on respecting the dead and being careful about what he said in the presence of other people who may not share his opinion. The trainee then began to boast that he'd been going easy on Harry and challenged him to a rematch.
Harry was not pleased, but allowed it and once again thoroughly thrashed the trainee.
His lunch break was his sanctuary, away from the dunderheads of half his office, but halfway through lunch, he was called out on a case which turned out to be a wild goose chase across most of Scotland. He got back to the office late, but he was elected to do the paperwork since the other Aurors on his team claimed that he wrote the best papers out of all of them. They were just being lazy gits.
Harry finished his paperwork quickly but was in a foul mood by the time he got home. Ginny had food waiting, but he simply gave her a quick peck before grunting, "I'm going to bed."
Ginny looked a bit put out, but Harry's mood let him ignore things like that as he hurried up the steps to his bedroom. He shrugged into nightclothes, turned off the lights, and tried to sleep – he was bloody exhausted.
But his mind was still racing, replaying the indignities of the day. He groaned angrily as he basically rewrote his report in his head.
Ginny came in as he was trying to bash his head in with a pillow. She laughed lightly, joining him in bed. "Losing a fight with your pillow?" She smirked.
"With my mind," Harry snapped back, not in the mood for teasing. He threw the pillow over his face, right after noticing Ginny's taken aback look. He felt slightly guilty for that, but he was just going mad.
Still, in a small apology, he reached out and took Ginny's hand with his own, stroking the back of her hand softly. "Bad day at work," he explained roughly.
Ginny didn't reply and Harry figured that he deserved no better. He fell into a troubled sleep. When he woke up, he noticed that it was about three o'clock in the morning.
He also noticed that Ginny wasn't in bed with him. That woke him up. He felt horrible, remembering how rude he'd been to his wife last night. If anything had hurt her and they hadn't made up…
He grabbed his wand and hurried throughout the house, peeking into doors and listening for her.
Finally, he heard mumbling from the kitchen and silently approached it. When he peaked in, he saw Ginny with her head in her hands at the table.
"I don't know what I did wrong," she mumbled to herself; Harry knew that when she was really upset she tended to try to talk her problems out with herself. "He's never carried his frustrations home from work with him before today. I don't know how to make it better. I want to help him."
Harry's heart sank, knowing that she was acting like this because of how he'd treated her last night.
"I've comforted him before, but I don't know how to comfort him if he doesn't give me a chance to see what's wrong." She ran her hands through her red hair. "Dad never came home like this to Mum; she always cheered him up. I thought I'd be better at this wife business. This is his first day coming home like this, but still… I thought I'd handle it better."
Harry had begun to step into the kitchen when a spirit swept through the room. The spirit of Sirius Black sped eagerly towards Harry's wife, spinning as crazily around her as a dog chasing its tail. Harry watched as Ginny slowly raised her head and smiled slightly, shaking her head. "He'll tell me what he needs to…"
Harry was surprised that Sirius was the one who chose to comfort Ginny, but then again, she'd told him that they'd gotten close during that summer at Grimmauld Place.
Sirius's spirit bounded away as Harry entered the room. "I'm sorry, Gin," he said, wrapping his arms around her and kissing her softly on the cheek. "I let work get to me. I won't let it happen again."
Ginny smiled back at Harry. "Just tell me what's going on and I'll help you out."
Harry nodded and kissed his wife sweetly.
Whenever Ginny Potter felt nervous about being a good wife to the love of her life, the spirit of Sirius Black, godfather to said love of her life, would always be ready to help her understand the enigma that is Harry Potter.
