It's not like that, dude. Family comes first to me, but he wants to go to some fucking world softball tournament and decided to plan his daughters birthday on the 13th rather than on her ACTUAL bithday which is two weeks before that date.
He's just being a fucking asshole. The other portion of my family taking this weekend adventure aren't pleased about it, either, because it interferes with their summer trip.
It was a tool move for him to throw it on that day, and try to use his daughter as the middle ground on his hater bullshit.
