how do you know when you're in love?

I think its a very profound question...How do you know if that special person is the one for you?Is it that you just know? I'm really confused..never having been in love myself...but i've tried to put down some of my fellings here...i don't know if this stuff will ever happen to me..but hey that's what poetry is all about right?giving voice to feelings that are cocooned in the deepest reaches of your heart? when a smile makes you forget everything, when a touch is all that you need to transport you to heaven, when words seem to much of a burden, when each day brings a new promise, when time seems to stand still......... and you are not yourself........ ThaT is LoVe....
