I don't think this is true.

Let me think back to when we met... hmm... (that was a while ago, wasn't it...)

No, not condescending. Actually, you were quite friendly. And you seemed to like me right away, which actually, most people do not.

It could be because your Canadian-ness is off-putting to Americans. Not sure about that, though, as Dave and I never had any problems in the States when we were down there. And you knew Dave, he could be very off-putting when he wanted to be.
