In the past few months, a much younger woman, much younger, has spent a lot of time with me. She initiated the contact, although I knew her many years ago, when she was an adolescent. Typically, we eat at a restaurant with friends of mine. She is a very attractive, highly educated professional who doesn't need my assets, if I had any. If I don't invite her, she invites me. But, there has been no physical intimacy. I don't want to hurt her feelings, or make a fool of myself, but I wonder if we are just friends.
