What mean of Love?

I often hear this word, L O V E ?? what exact mean of love?? anyone can tell me?
in my age, more friends has couple. maybe some of them has more than one. omg!!
I think love is one feeling from a deep heart that you cant imagine and touch that. but, how we can know that is love? for me, if i meet someone ,boy, my heart will beat fo fast, if like him of course.

but love can make you confuse , hurt, get pain , happy, and boring.
like me, yesterday I meet Mr.A.L in my school, he used uniform police and he is so charming, awesome and handsome. i feel like get miracle. i was melting on the spot, i was so happy.

Love is not a word. Love is not a thing. Love is gift from God that you must thanks cause it is combination of all feeling. Love is complete one . You agree?
so we must share our love everyday with smile to each other. love can make you know the mean of life.

what your opinion about love??
