I used the western toilet horribly wrong until I was 16
Did anyone notice what you had done?
My dad often tells me that I'm stupid and it made me feel lower than others.
Making mistakes allows you to learn what you value, what you like, what you don't want, and what you don't need. You moved on from the mistake and now you're a better person for it.
Ok I understand, but I'll still try to wash my ass better.
I think that you should always wash it, regardless. It was good that you learned the right way to use the toilet though!
