this is a riddle, its describing something (could be a thought a feeling, or an actual thing) im not posting an awnser cuz i want to see what other people think it might be, but if you really want to know than you can email me...

it imprisions some
and frees others
it could be hell for you
but a lifesource for your brother

some think of it
as a requirement of life
others see it as a social event
to talk about joys and strife

it is where some people go
to see their friends
and some people go
to plan life to its ends

but in reality its life
it can be harsh or kind
and when you finally get out
you realize it was all in your mind

what is it?
