I still make friendship bracelets...the right way.
I remember the pant rolling, too, where you folded it over and either tuck it in your colorful girly socks or roll it twice or so to keep it snug, as Ugly mentioned.
I also remember honeysuckles, which were half a lemon with a candy stick.
That's not a big thing, I know, but I have thought about those randomly off and on the last few years.
I remember Pogs (those were huge!), Garbage Pail Kids (they nauseate me now), those little rhymes where you did the hand-patting thing with others (Say, Say Oh Playmate, Miss Susie, and the like). I remember drinking pickle juice.
I remember when sleepovers didn't involve drinking and flirting and gory sex movies, but rather cheesy horror flicks and pillow fights. I didn't have many sleepovers.
I remember Cat's Cradle and other such games.
