Doomed Eyebrow

Me: Hello?
Amanda: Hey.
Me: What's up?
Amanda: You can't laugh.
Me: Okay.
Amanda: I mean it. You have to promise not to laugh.
Me: All right, already. I promise.
Amanda: *Sigh* My left eyebrow is gone.
Me: How?
Amanda: I don't want to talk about it.
...
Me: Well, on the bright side, it's a good incentive to get bangs like you've been wanting.
Amanda: I hate you.
