Charlie wasn't an uncaring person. He knew that that guy's wife needed her husband and not Charlie, so he grabbed the hand of the nearest person to him, which ended up being a teenage girl, who was walking with her friends.
After he hopped bodies, Charlie stopped walking and watched as the cop and the guy ran down the street in search of his wife. Problem solved.
"Vicky? Are you okay?" a girl asked, walking towards Charlie.
Charlie looked down at himself. He had chosen a body at random. He had no idea he had picked a girl. He reached up and squeezed one the girl's breasts. It felt so weird.
"Vicky?"
He looked up and saw three teenage girls looking at him. They seemed concerned. But just imagine how concerned they'd really be if they found out that a man twice their age was inhabiting Vicky's body.
