Is there a name for this sort of behavior? (Details follow).

I know this person very well. We aren’t friends, we are acquaintances, but we do see each other often because circumstances often throw us together.

It is the strangest thing…and I am not sure what to classify this (aside from being really rude). We will engage in conversation. He will say something to me and when I begin to answer…as soon as I begin to answer his question, he will turn around and start talking about something else! He does not wait for me to finish.

Example:
“Hi Rhad….I’ve been working on the Foster account and it seems to be going really well. Then, I think I’m going to take a break and go to Spain for a week. How about you…?”

“Oh, well…I’ve been thinking about——”

“Oh, look at that lovely red sportscar…I always fancied that sportscar. I almost got one when I was in my 20’s and always regretted that. Maybe I will find a way to (blah blah blah)....” for another ten minutes.

“Hey Rhad…do you have any recommendations for a good hardy flower for my garden? I used to grow violas, but they don’t seem to be working anymore. What do you think?”

“Well, yes…I really think that——”

“Oh…look at that guy! He looks like Frank doesn’t he? Remember Frank from the pub at Cardiff? Wow, what a resemblance…(blah blah blah)” for another ten minutes or twenty forgetting completely that I am even there and that I was supposed to answer a question.

Folks…this is almost every time. This is not once or twice. As soon as I begin to answer a question or start a conversation…he will look away and find something to distract him and start talking about that. It is unbelievable. At first, I thought I was imagining it, but I actually began to make a note of it. I honestly think there must be some sort of kink in his psychology.

Has anyone ever experienced this? Does anyone have an idea psychologically what might be going on?

Thanks in advance.

P.S. He is not “hyper” or anything like that…but he is a “Type A” personality.
