Mobile phones
She called me this afternoon. I picked up the phone.

-Hi, darling.
-I can't hear you.
-I said "Hi, darling."
-It's so noisy here, I can't hear you.
- Why did you call, then?
-What?
- Why did you call me now, if it's so noisy?
-What? I can't hear you. It's too noisy here, I'll call you later.
She hung up.
