to keep or not to keep

there are things better off left unsaid... so goes the phrase.
why? i don't want to keep it.
would knowing something hurt more than being lied to?
frankly, i'd rather know. let me decide what is painful and what is not.
but still we keep... because, its not so much we are afraid of hurting someone.
its that we are more afraid the consequences of telling might hurt us back.
you see, we are all selfish creatures in the end.
so i guess its just easier and less painful to keep than it is to tell.
i have seen things go bad with just a few words and rampant imagination.
keep...
but people aren't stupid. eventually, they'll catch on.
and the longer you keep, the fouler it gets.
don't keep...
i don't know.
what are you not telling me?
