Using imagination I would say it is a very sad good-bye scene.

The guy on the left is so boring it put the guy on the right asleep.

The guy on the right can't believe the guy on the left is so stupid.

Left young guy, very excited, has just told parent on the right that he's leaving home tomorrow.

Left guy is telling right guy about how he made this great investment, and has invested all his money in Circuit City.
