[This was inspired by the "Do you sing in the shower thread", so I'm not entirely to blame for this. Mostly, but not entirely.] So - have you ever taken your guitar with you while you went where the King (or Queen) Goes Alone? I have. Many times. My wife finds it appalling, but I find it utterly natural. I mean, what else are you going to do in there (other than the obvious)? Why not take advantage of a few extra minutes of quiet time? (No discussion of how quiet it is, please.) Honestly, if I could get away with it, I'd have my guitar in my hands all day long.
