There are so many other ways to enjoy life that don't end up with you moaning in front of a toilet or taking care of the person who does. I have friends who party, and that's fine for them. I see it as loud and annoying. I like to converse, and usually the music is just too loud for that. I'd much rather enjoy a meal before writer's meetup and make a trip up to the lake and enjoy a talk-and-walk.
I'll go to the parties I need to, but I tend to help hold up the wall and make sure people don't fall over themselves. I'll be momma when I need to, but I still shouldn't need to.
