I think you have a valid point. There is a slight veneer to me when I first meet people. It does fade as I get to know them, but there is that level of misleading and having secrets that has made me lose so many friends since this has happened to me. I always tell people that my attitude is because I have nothing left to prove to anyone since I have been there and done that, but sometimes I feel that the exact opposite is true.
