Mistakes

"It is not what your deeds are that makes you,Its your mistakes"
We all are humans.We are not perfect.We make mistakes,sometimes small sometimes big. Whether it is a mistake of trusting the wrong foe or fooling a friend or simply doing soemthing absolutely stupid like videotaping ur sister's firstnight and selling it over the net.You might ask what is my point exactly? My point is when others make mistakes we don't forget or forgive easily but when we do the same mistake we expect them to forgive us easily as if its not a big deal.Why is it that we expect the things out of others that we can't even give to them? Is it a humanly flaw or somehow the effect of community on us?
