nobody is perfect. we are all lacking in things that usually people can't see. from day to day we learn to just embrace them or simply close one eyes and decide to ignore them; not completely, because it's a constant battle within ourselves.
while we struggle to ignore and embrace them, there are also people who constantly there to remind how flawed we are. how lack we are according to their personal standard, or society standard.
we hardly say that it doesn't affect us but the reality is already ripping our feelings in half, at least.
