Are you shy about your music taste?
In offline life, I mean.
I do get a bit shy about my music taste and tend to turn the volume down when someone is at home. There are certain bands and artists that I would never play to someone else as the reaction would be "what the f*** are we listening to" (I have some very musically unadventurous friends).
I think it tends to go like this - when I listen to my music by myself, I think "this is awesome" but when I play for others, I find myself saying "hang on, it gets better".
Also, when I tell people that I am into stoner/doom metal, they think I am weird
