How do you know when you're in love?

How do you know when you're in love
is it the crazy things you do
is it the fact that my heart skips a beat
everytime that i think of you
Is it the fact that I can't sleep at night
when your image is in my head
Or is it the fact that I can't stop smiling
after every word that you've said
Is it the need to hold you in my arms
and keep you there forever
Or is it the fact that I wrote you a poem
and sent it to you in a letter
Is it this awful feeling deep inside
whenever I have to take you home
Or is it just being here without you
that makes me feel so alone
Is is this hunger deep inside
that longs for your kiss
I am so happy that I'm in love
for there are so many things I would miss
