Peter and His Mum

Peter invites his mum for tea. She notices his flat mate Joe is slightly camp and although she suspects Peters gay, he denies that anything is going on and that they are only flat mates. A week later Joe says to Peter "Ever since your mum came for Tea, I cant find the frying pan". Peter emails his mum " Dear Mum, I'm not saying that you did take the frying pan and I'm not saying you didnt take the frying pan, but its been missing ever since you came for Tea. Love Peter" ... His Mum replies ... "Dear Son, I'm not saying you do sleep with Joe and I'm not saying you do not sleep with Joe, but if he was sleeping in his own bed he would have found the frying pan by now. Love Mum."
