He does too. He doesn't behave the same way with everyone else that he behaves with us. Even that guy who wrestles with him on Saturdays still gets an eyeball when he comes up to Opie to say hi.
(Opie lets him say hi, but its like "well, I guess I DO know you, so I guess you can say hi if you really want to, although it wouldn't bother me if you left me alone.")
If there was a time when he didn't like you, it was when you rolled over on his paw.
