Sometimes, just sometimes.. it is possible to feel that you're so frustrated that very very little can appease you.
Sometimes, and only sometimes, you can see someone banging his head against the wall countless times and not know what to do to help him.
Sometimes, you don't want to help. Want them to learn themselves and wonder.. when you yourself will ever learn.
Sometimes, it is far easier not to care than to lend a hand and help where you're not needed.
and sometimes.. not facing a problem is really the best way.
