Is it just me?

A while back I tossed a stack of about 50 business cards that my neighbor down the street gave me. You see I would be welding a quarter panel on a car and he would stop by to give me "his welders" card (meaning the guy he pays to weld things for him). Totally ignoring that I told him I used to train nuclear power plant welders and certify boilermakers. If I was prepping a car for paint I would get his body mans card, he would ignore the collage of cars I painted in the early 80's posted on my wall from when I had a small body shop in college. This goes on CONSTANTLY no matter what I am working on with this guy. I could be down to the last wheelbarrow of landscape rock and I get his landscapers card! Is this his way of trying to fit in or something? Am I the only one who this happens to? Gotta be a guy thing of some sort?
