If somebody leaves u with lots of tears.. then just save them safely. later wen a person who cums 2 u with happiness, then just compare the saved tears and present happiness. If happiness overcomes your tears .... Then i am sure you have found your BEST FRIEND.
Friendship is the hardest thing in the world to explain.Its not something U learn in school. But if havent learned the meaning of Friendship,U haven;t learned anything....
