Learning to stay away

when people come close 
it gives you joy that someone cares for you
it gives you an everlasting happiness

but in no time it turns into sadness
when they just  go away from you
and you sit thinking all day why did they go ??
and you realize that its the game played by the life
which is ,when you start attaching to people 
they become so important in your life 
they just leave you and go

but the heart is now strongly ready to stay away from people
with this promise you move ahead 
but sadly knowingly you break the promise 
knowing you attach to the person which only hurts and hurts
