Dad was a "closet" piano player. He was taught classically and would lock himself away with the piano when he needed escape from the family (just Mum and myself). I never worked out why for him, music was a selfish interest in that he never played to or for anyone. My half brothers and sisters (from his previous marriage) learned music to varying levels. One of them was a working guitarist playing in bands and studio sessions on and off.
My first "go" at the bass was half-ars3d to say the least. I had no inclination to learn properly but instead knocked around with a family of brothers who were all multi-instrumentalists. The older ones were living off it nicely. I got by as a stand in when the talented ones were creating and I never had to learn to play a known piece. It was all [s]derivative[/s], er, original - ahem.
When I did what the OP did and tried to jam with dad, we could not find any common ground whatsoever and both quietly resolved never to try again. I stopped playing for many years after that.
When I got over myself years and years after, my new approach was to aim to get people moving rather than gratify myself with how I sound in my own head. I am still working on that. My partner's grandchildren often hang out when I practice and I've seen them shaking it when they think no-one's looking. That has to be the best feedback for me. It encourages me to keep at it.
