You should ponder upon why you don't want to tell your mother. She has seen stuff coming out from both ends of you of the kind that you maybe never will get to see. Raising you, she has seen *everything*.
Clogging a hotel room loo is caused by four things:
1) pooper being an adult making way too huge sausages (which really isn't a problem, since they do dissolve sooner or later, but ask at the desk for help),
2) pooper being an idiot not flushing down the big sausages before using a kilometre of loo paper (ask at the desk for help),
3) pooper not really pooping but being even more of an idiot flushing down something that is not one of the only three things that should ever ever go down a loo: pee, poop, and loo paper (fess up and ask at the desk for help),
4) hotel being a really cheap one not performing running maintenance on drains and pipes, and the problem has been building up over time by idiots flushing stuff they shouldn't flush - like tampons, left-over dinner, and unwanted puppies (if you did none of that, make a scene and refuse to pay).
