I heard of a legend of a woman covered in blood coming out of a puddle of water if you were near and kill you if you disrespected your parents. I was sort of the obnoxious child, and our shower mat covered the drain so as I took showers there would always be a puddle. I worried that this woman would come out of the puddle and get me, so I'd always glance at the toilet water every few seconds from behind the shower curtain, and I'd hurry up in showers always thinking to myself, "I love my parents we're best friends!" thinking she can hear my thoughts and she'd believe me.
