I hate it so much. I can't stand standing in the bathroom in front of a mirror and fiddle with my teeth. That whole experience is just wholy depressing, and then the foul taste on top of that. I try to at least brush and use mouthwash when I wake up and am groggy enough to not mind that much.
I mean I couldn't do that either, not for very long at least. I have the tendency to walk around aimlessly when doing something like that (same when I'm on the phone), which means I have to clean the floor after. So mostly I either brush my theeth in the shower or I sit down/lie down.
Damn, I just noticed that my theeth brushing habits are probably very weird, bit hey, at least that way I do it 2 - 3 times a day.
It's not the mirror (for me at least), it's the whole room, and the feeling of messing with the teeth, the scraping in the ears when brushing, all that.
Sometimes I put on earphones with an audioshow or something, which makes some aspects slightly more tolerable, but others even worse.
