I had a big party my mom threw for my 40th birthday because she has a huge house and lives in the town where I grew up and half the people there never left. Another good percentage of them moved back. Anyway, I mostly ended up only talking to a handful of people who sort of monopolized me, so it was less fun than it could have been. Don't get me wrong, it was great talking to them since I hadn't talked to them in ages, but I ended up wishing I had talked to more people. I haven't had a party since. Next year will be my 47th. Maybe if my mom is still around when I'm 50 she'll do it again.
