@alex: Hey, Mink? You’re not mad at me, are you?
@mink: And what would make you think that?
@alex: I don’t know. I was just worried that you might be mad when I asked you to check with me before buying a plane ticket to come out here. You haven’t messaged since then.
@mink: I’m not mad. I would have thought you knew me better than that.
@alex: Err . . . Is that a joke? I can’t tell.
@mink: Sometimes it’s hard to tell someone’s tone online. Anyway, too busy to talk now. Catch you later.
