My father was killed. He died a hero so there's always some celebration involved with the mourning but, generally, it turned into a day for Starfleet to look back and remember those who lost their lives in service to the fleet. So, in a way, yeah. It wasn't completely bad. Bones made me appreciate it a little more and Sam used to try before he ran away from home.
I don't know. It wouldn't have meant the same thing here. It's just a day so... I guess it could've just been my birthday without the other stuff.
