"Are you two dating?"
Double take. Did I hear that right? I look at my daughter who is looking a little confused. I realize I did hear it right. "Well, she's dating a very nice young man named Joe."
"No, I mean you two."
"Well no, she's my daughter." ...a slightly uncomfortable silence from them trying to figure out if I was pulling their collective legs and the two of us wondering if they are serious. Maybe I just look like a dirty old man.
