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.
A true friend understands when you say I forgot. Waits for ever when you say 1 minute . Stays when you say Leave me alone . And opens the door even before you knock!!!
