In my family the birthday person gets to pick the meal, which I always enjoy.
I also use my birthday as an excuse to get together with friends. There are more people I love around than there are hours of the day, so having birthdays as a set excuse to go to dinner and spend time together makes me smile.
My dad coaches a high school aged summer baseball team, and my birthday is right as they're in the season-end tournament. He decided to retire from coaching this year, so I really hope he's not around on my birthday and we'll have a late celebration, because it means they will have made it past regionals if they're not back.
