I recognize this a lot. Especially when I was younger I used to ask these "stupid" questions from time to time. I've kind of learned to adapt to other people and shut myself up when I feel the urge of asking "stupid" questions come up.
For an example, i'm a good electrician, and then everybody expects me to be "the handyman" and be able to fix cars and the like. I hate cars.
And I can't tell the difference from rear-view mirror and an exhaust system. OK, exaggeration, but you get the point.
