Wow! I just met a bad ISTp. I usually really like them, but I'm now understanding there is a lot more than type...

This guy complained constantly (in a whiny way). He would interrupt me to say "sorry, my back hurts" and stretch. He also complained of various other things such, everything from the weather to the city, etc. And he let his parents tell him what to do and was late because his parents were dropping something off. This did not come off like a cool "bad boy" but was simply "bad." He seemed somehow spineless and wimpy, and I couldn't understand how any ISTp could be like that Then he seemed to be waiting to see if I'd pay the check. I offered to split and he excitedly took me up on it. My faith in duality is being shaken...maybe other things are more important than socionics?

And he also complained about all the things I like and he seemed like a total stick in the mud. Seemed totally set in his ways too, while also being . How is it possible to be a wimpy ISTp?
