If she slapped your hand definitely go to the camp director and tell them that. Tell them all of what you said...she shouldnt be touching you period. Y ou are not being oversenstive at all, the director will handle it.
i'm just going to cut straight to the chase, basically i have these half siblings, (this mostly has to do with one of the brothers), and really just started a relationship cause we didnt know who the other one was, i found out who my dad was not that long ago and so we didnt even know eachother...
