I've never been to one, personally. And, frankly... have no desire to! Lol!
With my friends, our idea of a good time is a small get together... a dinner and dessert, some games (Apples to Apples, Balderdash, Boggle, Scrabble, Uno, and MadGab), and a movie. Sometimes if it's just us girls, it's a sleepover and we craft (usually crochet, which is easiest to do while watching a movie, other times we changed it up with a pottery wheel, jewelrymaking, and cardmaking).
