During my highschool years, My mom set up a garage sale one morning while I was still sleeping and I woke up to her already having sold 3/4 of my childhood archie comic collection for like a mere 10 bucks.
I was mad at her for DAYS.
That sucks about your birthday too dude, the older I get the harder it is to get people out for a birthday and exponentially harder to expect people to stay up late.
If I'm ever at a birthday I always make an insane effort to not be a party pooper and go along with whatever the birthday boy/girl wants to do.
Maybe everyone was just partied out after your epic wedding bash?
