i think you should shave, because, 1. you're going to have to some time. and 2. it's hella embarrassing to have people walk up to you and say you've got some dirt on your face or to have a family member say you need to shave EVERY DAY.
i shave, and as long as you keep shaving it wont grow back! i mean it will eventually but.. eh, you know what i mean.
i say shave.
