The person who cares lot for others.. is the one who needs more care than others. 

The person who makes other laugh & smile all time..is the one who holds lot of pain in heart. 

The person who tries to be a good friend to all...is the one who needs a best friend for own.

The person who always smiles & says I'm fine..is the one who is broken at heart but still strong enough to believe that at the end everything is going to be fine :)
