Captive audience

Aidan’s phone rang again. No immediate reply, but after a few rings, a click and Aidan’s voice once more with a single question:

”Don?”

He didn’t get any further with his opening, because I immediately launched at him.

“Well thanks a bunch for ringing me back mate! Worried about your phone bill? You always were a tight-fisted bastard! Or don’t you want to speak to me? Is that it?”

”Really Sorry Don, truly I am, mate! The thing is, I can’t make outgoing calls... I can only receive them!”

“Sounds like a bloody strange kind of captivity to me!”
