She tells me the reason she helps people is because end of the day, she may get to see them happy, a some sort of compensation for her own unhappiness.
It sounds sappy in written words, but I wanted to cry. I really did. Her eyes were getting red and a bit watery, but in my whole life, I've only seen her truly cry less than 3 times.
Like giving your friends surprise bday parties all the time when no one does it for you. She prolly don't see it that way, but somehow I think that's what she yearns for deep inside. For some little bit of happiness to call her own.
