I'm now a uni-boober and remember back to when I had two and the best part of the day was getting home from work and the first thing you'd do is rip off the bra. Imagaine - getting home from work and ripping off the boobs! What freedom!
I didn't know how I'd feel when I was pre-surgery but now that I've been a month with just one I'd definitely feel more even with none. And then you could pick your cup size for the occaision - B cup for shopping/exercise, D cup for evening out. No more trying to 'match' the remaining one.
I'm all for flat!
