When this mom is upset with her daughter, she asks Reddit:
My daughter is 14 years old, I'll call her Rosie to maintain privacy. Shes the middle child of 4 kids, with my oldest sons being 16, 18, and youngest son is 10. She is my only daughter.
She has high functioning autism and is starting to model some of the boy's behaviors, and to the next level. She has some sort of a fart fetish.
She laughs at farts, looks up every fact on farting(including foods that trigger gas, etc.), watches fart pranks on her ipad out loud. All without any regard to the context of the situation. I wish I was joking.
I have taught her and our sons table manners. I've been teaching them and reinforcing them since they were little.
They were told to say excuse me when they belch. cover their mouth when they cough and sneeze. Close their mouth when they eat. Very basic table manners. Some of these things I tell her each time it's like I told her the first time.
