How to sit over there.....???????

Well there are four groups at my theatre camp. The snobby girls, the really good people, the lil' youngsters, and me and my two friends who all have good parts but not "good" seats. Every morning all of the groups make a circle, and we're friends with some of the really good people. We want to sit with them, but don't know how to get up the courage or how to "act/behave"
