Hello swimfan67, I see this is your first post so welcome to PC!

I hope you find your time here to be of benefit. Once you have 5 approved posts, you will be able to enter the chat room and talk to fellow members. There is almost always someone online to chat with.
It sounds like your friend reacted far too defensively for nothing to have been going on. I think he was caught doing something inappropriate and lashed out at you for pointing it out. I agree with eskielover - he should be the one apologizing to you.
