That is so strange! I had to laugh though, because years ago I was 19 and dating a man Way older than myself. In fact, his daughter from a former marriage was older than me. We used to hold hands in restaurants and have to admit in a very immature way (well I was 19) I got some thrill from people staring at us because he obviously so much older than I was.
Anyway, we would be obviously holding hands as boyfriend/girlfriend and he would say loud enough for everyone to hear, "You are the one for me, I want to spend my whole life with you...too bad you are my daughter!!" and then we would both crack up hysterically! He obviously had a very - em - different sense of humor and I was immature enough to find it hysterically funny. Anyway, the headlines of this article reminds me of this guy.
Had to edit to add that it was Not this guys fault that we ended up dating. I pursued him relentlessly until he finally gave in. Yes, he should have known better, but I really hold myself ultimately responsible. I knew exactly what I was doing.
