Our telephone announces who is calling. I rarely even move when it starts ringing anymore unless it says it's my husband or one of the kids. Any other calls are usually telemarketers and I don't want to talk to them. If I do get a call from someone important, I can always call back.
But I did have to laugh a little with your story with what happened to me. The other day at work things were so crazy I just couldn't get away to use the bathroom all afternoon. Drove home after work (luckily it's only 2 blocks from home) and first thing I did was take the dogs out to the bathroom. By the time they were done and I got them back in the house I really was rushing to get to the bathroom and undo my pants, just about to sit down and the stinking doorbell rings. No way was I going to stop at that point and the stupid idiot kept ringing and ringing the doorbell. It finally stopped, but by the time I got to the door whoever it was was long gone. It was a salesman for the local phone company and came back 20 minutes later and said that he'd seen me pull in so he knew I was home and why didn't I answer the door the first time. The nerve of some people!!!
