Let's say that Amy is interested in getting to know Jamal. She might walk up to him and say, "Hello, Jamal, how's it going?" She might simply smile at him and hope he gets the message. Or Jamal might find a little scented note in his locker with an invitation to a party for everyone at her house on the weekend. All of these are ways of communicating her message: I'm interested in you! It could be spoken words, written words, or no words at all.
