I think of his sort as a frenemy. He's actually a machinist by trade, which makes him an expert in all things. He'd come by and offer advice like he's an expert on the topic and be so far off base and wrong it would be obvious he knew absolutely nothing about it and had never done it at all. Then I would have a blast roasting his ideas in detail until he'd get a shit eating grin as he slowly realized I had once more exposed his ignorance. It's not like I critique him on machinist details because I stay in my lane. I designed a cantilevered overhead trellis for his sister and he stopped by to advise me that I shouldn't put in the end posts first but rather should be just starting at one end and install one by one in sequence. Who needs all them stupid string lines right? So I enjoyed ripping on his ignorance for the next half hour.
