Dare: Your character takes on a Jekyll and Hyde persona if they see their reflection for any length of time more than an instant.
BP: They are extremely narcissistic and concerned with their looks
DBP: This occurs in every possible reflection, be it mirror, water, or hazy polished metal/plastic
TBP: He/she has already tried to 'break' the curse before by disfiguring himself in some way, despite the propensity to narcissim
COOKIE: S/He has to take extreme measures and exist in complete darkness or hermitage to function normally (which is a double edged sword... since that's nowhere near a normal life by regular standards)
WITH MILK: Or is there somewhere that is regular as a standard?
