Is this love????

Often wonder what is love? I can understand it is no good in trying to define.. Still sometimes I feel this is more a 'misunderstanding between two fools than something special'.
At times I feel love doesnot exist at all. And there are some other moments when I feel those long waitings.....those loving and caring SMSes and all the more.... the reminiscences that make you smile....
