sheesh, first of all everybody runs around yelling, screaming and giggling and whoever's it (you) has to catch someone and when you tap them you yell, "tag, you're it" and then you run like hell so they can't tag you back.
lot's of fun unless when you're nine or so you're looking behind you and run into the back of a pick up truck and black you eye real good and then it's not fun any more.
