Halloween made me twitchy.
I didn't like the day. Objectively, I knew it was the day my little brother was born, but before I actually met him it was defined by being the day my father killed my mother.
Yeah. Not exactly good associations.
Fortunately, the years padded that, and I could now think of the day as Harry's birthday first and familicide second.
Well, actually, Halloween was usually the focus of the supernatural baddies. So now I thought of it as Harry's birthday/Murderfest first and familicide second.
Harry probably thought of it just as Murderfest.
Which must really suck.
