the neighbor who knew too much

I know that my neighbor does not use toilet paper when he pees. You may be wondering, "How can she know this?" I'll explain... but realize that once you have this information your life may be at risk as well.

I can hear my neighbor pee. It's clearly a male because the sound of a long stream hitting the bowl of water is very distinct. Much like filling my watering can with the hose held a couple of feet above. I can even hear the last drips from him shaking it dry. Guaranteed: he does not use toilet paper.
