Relationship is a.....

Lately I start to feel relationship is such an annoying issue and disaster, why ppl pursuing relationship so much?
It's emotionally influenced, up and down, it's so different from work that what u get is highly possible totally different from what u devote.
Though, ppl still pursue it... don't know why.

Can't life and things be easier? Why do we want relationship?
Yeah, it's good to have a company to share things and dong things together, but u'll never know when u fall into hell.
