People are talking about people??? (Please help)?

Basically people are talking about people, like I hear them whisper but this girl I know won't believe it. For some reason they think we're lover kept undercover, I mean like I try to ignore it but they keep pestering us saying that me and this girl laugh a little too loud, stand together a little too close and that we stare at each other a little too long. I wonder if their seeing things that me and her don't. Should me and her try to give them something to talk about???? How about love?
