I wrote this on April 2nd to celebrate LH's 75th birthday. (if I had been writing back in Feb, I definitely would've written this on the actual Leap Day!) I edited a few things if you remember reading this on Tumblr.

It was very early the morning of February 29th (the day that only comes once every 4 years) The birthday girl had woken up early to see the sun rise.

As the sun rose, She reminsied on how the past 4 years had been for her and her team: Losing her partner,

Almost losing her life more then once,

Watching her team get blown up and nearly killed,

Disappearing for 9 and a half months,

Returning in stunning fashion to save Deeks and Kensi's wedding,

Eric's undercover mission,

Finding out one of her 'orphans' had turned evil, (and almost losing her life, and Callen's, and Kensi and Deeks's lives in the process!)

Stopping the blood feud between the family that cost Callen his mother and his chance at a normal life.

And chuckled, because despite all of that, her agents were still intact, and She was still alive.

She poured a cup of tea, and raised it up, and proudly said:

'To hell with these last 4 years!'

Additional note: Some skilled digging by Tess DeCorsi revealed that, by very closing looking at the dates on her ID in Season 2's Black Widow, Hetty's birthday is on Leap Day! Ain't that cool?!
