Wisely said

Best friends are fully aware of how retarded you are;
and still manage to be seen with you in public!
- Unknown Wise Person

Friends are the ones
who will consider leaving you
when your world is falling apart;
but best friends are the ones
who will stay with you
when your world is falling apart,
even if their world might fall apart too.

Best friends are those
who treat you kindly behind your back.
