Ah cr@p, I started to answer that yesterday, and the dog rang.
Most people, of course, would think that he mistyped and was saying that the Phone rang … but this would be wrong. The dog did indeed ring.
Steve & Ruth got a really cute dog a few weeks ago
(photo forthcoming) … named Polly (short for Polygon, I think) … and they’ve trained her to ring a bell by the kitchen door when she needs to go out.
So while most people would more often get interupted by a phone ringing, Steve & Ruth will get interupted by the dog ringing.
Update: Added a picture of Polly.
