When you are dealing with these people instead of confronting them you can use body language that they should pick up on sub-conciously. I’ll list a few that I use on a regular bais (works to for people you are not intrested in having hit on you). Turn you face away from them while there speaking. Make sure you are not pionting anything towards them (feet, knees, hands ect). Chew ice, its a sign of anxity. Slup if you want to look tired. Other than that I would sugest an awsome fantasy life you can tune into when you need to tune someone out.
