Overview
Today, you won't have to worry about your friends misinterpreting you -- they always know right where you are coming from. However, you do need to watch out for a new person on the scene. They're not used to all of the verbal short cuts and inside jokes, and could easily misinterpret what you say -- and even make some negative assumptions. So until they get the knack of how things work, try to be as low key as you can. Invite them into every conversation you have.
