How do you know when you’re in love?

You think about him/her all the time. You crack a smile whenever you think about this person. You have feelings of elation and joy and you can't wait to talk to them. You find yourself thinking about them before bed and when you wake up. You can't imagine your life without them. You get butterflies in your tummy. This special love takes you by surprise and knocks you off your feet so to speak.
