'How do you know you have chemistry with someone?.....It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone...You can call it anything anything at all..You can say that it's right you can say that it's wrong..Let's just call it love. You call it what you want call it emotion. Let's just call it love..You can call it a feeling call it a notion. Let's just call it love!'
