What is the probable relationship between the two speakers? [br] [originaltext]

F: Why are you wasting your vacation inside, in front of your computer?
M: I’m not. I’ve been waiting months to have time for the Internet and computer games.
F: But ... but you can’t spend your entire summer doing just one thing.
M: I’m not. I’m doing many things--I’m sending e-mails, I’m chatting in chat rooms...
F: Right! But I’ll bet you’re spending most of your time playing computer games-a time-wasting, mindless activity.
M: No. There are many activities: role-playing games, arcade games, adventure games, strategy games...
F: All time-wasting and mindless.
M: No, I disagree. Chess, for example, requires a lot of thinking.
F: It would be a lot healthier if you played it in the park.
