Sounds a bit like the owner of one of the units I do on a regular basis, apparently she was blaming me at a body corporate meeting for progressively breaking her down pipe with the whippy. Fortunately I advised my contact when it started happening, and she kept an eye out, and at the next meeting was able to say that it was the owners own children who had being jumping on the pipe. The story as relayed to me that one owner was very embarressed and was very quiet for the rest of the meeting.
