friends and love

Some says "Love is nothing.."
Then how this word is surviving from so many millenniums??

Many says "There is an age to understand Love.."
Then why a kid cries departing from his mother??

Everyone says "Love has no definition.."
Then how can we define Friendship??

I say Friendship is the another name of Love, It teaches us the meaning of Love,
For me you, my Friends are my Love.
Love you all...
