Before we went to Buenos Aires I was thinking about it but once arrived I never paid attention or noticed anything when I flushed the toilet. Now I wish I would have. I would have loved to flush for the whole apartment building we stayed at. It would seemed to others as very strange request but it would have been all in the name of science. Uchg! No .. on other thoughts, I think I just stick with flushing my own. Over and over again.
