It hurts to love someone when we can't tell them what we really feel..because sometimes we get hurts without them knowing. we get jealous even if we have no right to feel that way. we want their time even we are not in the position to demand for it. although our heart are breaking in silence, we still continue to love then because somehow in this hurtful love there is still hope of having simple moments with them even if it means being just a friend..
p/s : forget all the reason why it won't work, and believe the one reason why it will :)
