Subway Lines

It is tough to watch teenagers in a Subway line. Sure they are full of energy and they all want to talk to each other at once. What I am talking about is when a girl and a guy are together. I see this all the time. The guy stands behind the girl and wraps his arms around her. He pretends he is a human brassiere, squeezing and lifting her chest, blows in her ear and whispers something. I want to get up and tell him to show some respect. Am I wrong?
