AM: Here, Sean, don’t use those towels. Use this one.
Sean: But I like those towels. Why can’t I use those towels?
AM: Those are guest towels.
AM: They’re for guests.
Sean: Am I a guest?
AM: No. You live here. Here, here’s your towel.
Sean: Oh. (disappointed) Why can’t I use the pretty towels?
AM: Why indeed.
AM: Here. (hands over the pretty towel) Be my guest.
