pain.. is when something with a force is inflicted on you and either causes you to tear up, in other cases scream, but..always..the one who keeps it all in. sometimes, pain is caused by anger, a forceful emotion sometimes kept inside, causing you to possibly inflict this pain on yourself..resulting in slight happiness, but for a small extent of time. To sum it all up, pain doesn't make anything better for a lifetime, it's only temporarily.
an example for pain.
just cut yourself and find out..or get someone to put you in pain..
