Growing up, I was okay with sleepovers, but I would've much preferred to not go. I honestly don't understand the appeal. You have to sleep in someone else's house in a bed that is never comfortable (or sometimes on the floor), you're deprived of sleep, you can't shower in the morning (which I require to not feel disgusting all day), and there's never anything appetizing for breakfast. (Or if you want to shower you have to bring all your stuff with you, and a towel, or else you have to use someone else's towel, which like the bed is never comfortable). Also, I always wake up at about 7 or 8 am, no matter when we all go to sleep. So while everyone else is passed out until noon (something I have never managed to do), I'm laying awake starving, hoping that there will be more than just disgusting cereal for breakfast. Conversely, I have no problem at all sleeping in hotels.
Yesterday one of my friends invited me to a sleepover held by some of her other friends. I was kind of confused because we're both in our 20s, and she's married. I thought I was finally done with that stuff . So I tried to decline without my disgust being that obvious, and of course I was pestered as to why, why, WHY would I not want to sleep in a stranger's house when I have a perfectly good one to sleep in, complete with boyfriend and comfortable bedding. So I basically explained what I wrote above, and just got a bunch of faces staring back at me and some "wow, what is your problem"-type comments, but I don't really care. I'm not going, so victory is mine!
