The greatest trick I ever learned in dealing with someone you're sleeping with alot and you really like him/her, but you're not quite sure if him/her likes you the same way is to mouth the words "olive oil". If that person says "I love you too", then you're in. If that person has a shocked look on his/her face, then you say, "Olive oil, baby. Let's get the olive oil." (I know that's an old one, but that's all I could come up with and I felt like posting something)
