I guess this is an annoying habit. (at least it was to my ex-wife) I like to make my surroundings a drum kit.
I tap a lot on things,or am doing double bass stuff. Much of the time I don't even realize it. I think for the most part I have broken myself of this habit out of respect to her when I was married,but yanno...now being single again all bets are OFF! lol
Other annoying habits I have,snore...sometime make silly sounds in my sleep...like to keep cd's,book,or dvd's alphabetized or in certain classifications. I'm sure I have a ton more. Oh well yeah,I have a sick sense of humor & probably say things I shouldn't say & just keep them to myself instead.
