Unexpected Phone Call

My wife and I purchased a wooden toilet seat to replace the avocado plastic one in our cloakroom. I installed the new seat and put the old one in the garage. At least two years later, I received a telephone call from a lady who asked whether I could supply her with an avocado toilet seat to replace a broken one. When I asked how she came to ring our number, she explained that she was trying to contact a local hardware shop. (I checked later and discovered that the shop's number differed from our own by one digit, although this was the only occasion when we have received a call intended for them.) I told her that we did, in fact, have an unwanted avocado toilet seat which she was welcome to have if she wished to collect it. She gratefully accepted my offer.
