But I don't want to dance with you

I've been doing a funny little dance with one of my customers. A couple weeks ago he called and was completely rude to me. He belittled me by saying I hadn't been with the company long enough to know the product. Needless to say, I was very insulted. And that day, it made me really, really angry. We almost go into it over the phone. He happened to attack me at a really bad time. I had been working very hard the weeks prior and my patience had worn thin. Plus I really don't like being belittled (not like anyone does). So I almost yelled at him on the phone but managed to just cut the conversation short and get off the phone.

Then I didn't talk to this customer for a couple weeks and had pretty much forgotten about the incident. Well, he called yesterday. I almost didn't remember it was him except that he was acting strange. Of course I finally remembered why he was acting strange. He had been a complete jerk to me only a couple weeks ago. And he had no reason to be a jerk; I had been right about the issue all along. So now he and I are doing a dance. It's the be-way-too-polite-in-order-to-show-you're-sorry dance. We're both obviously over the tension we experienced a few weeks ago. But we don't know each other well enough to just talk about it and be done with it. So we act really nice to each other. WAY nice. It's really quite humorous.
