My room mate for almost 2 years in my dorm from work,sometimes annoys me,when he tries to pinched my side.I have already complain to him that I do not want his pinching cause it hurts my skin and it produces some bruises later.He always do it to me especially when we have some sort of jokes.The last time he done it have made me punch him that is why he does it like a joke at times.I do not know his motives towards me yet I know he is straight yet I do not like his actions of pinching me.I know women does pinching towards men but he is an exception.We are the only ones in the room with a double deck.I just do not know because I am a deep sleeper and I have never notice any wrong doings towards me.What can you see about this myLot friends?
