Just think of it as another day. Don't put any emphasis on it. Your building up anticipation for yourself and geeking out over it. Don't psych yourself out over it. You might be setting yourself up for a huge let down.
Don't be disappointed if he doesn't acknowledge the day. I'd hate to see you cause more pain for yourself.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
