Let me traumatise you guys with a memory of mine with toothbrushes!!! We were visiting my granma's as always and i put my toothbrush by the cupboard by the sink. One day i went to use it as normal. But then i got a huge canker sore and it was so painful i had to go to the doctor. Then i continued using it so i keep my mouth hygenic, right? Well turns out my granma had been using the toothbrush to clean the toilet and my sore kept getting worse cuz she kept cleaning the toilet with it.... The toilet my granpa uses. He has colon canser and has a constant diarrh0e...... Well my granma is kind of, yk, old so she never questioned why there was a brand new toilet brush in the cupboard. So i learned about it and puked and cried the whole night
