Love is knowing that you have that "call of the night" -- where you have someone to call to say good night!
Love is knowing that when you are down or upset, happy or elated you have someone to count on to share your sorrow or happiness.
Love can take different forms - the one you have for your mom, dad, sis, bro....but when you meet that special someone your heart will say "Kya yahi pyar hai?"
I personally think Love is a beautiful emotion between two people that takes understanding, togetherness and time to help blossom. If done in the right way, it can be absolutely mesmerizing and beautiful and if you fall for the wrong person a life full of heartache.
Take your pick.
