After Pinter

The sound of a cellphone with an annoyingly persistent ring is heard from the other side of the office. It rings for a long time.
Me: Someone who doesn't answer their phone has stolen my ring tone.
Workmate: Are you sure it's not your phone and you've left it in the kitchen.
Me:
I look at my desk. I look for my folio which has my phone in it. I look sheepish. I get up and come back carrying my phone.
We both laugh a lot.
