With my husband in My life

I told my husband when you raise a child is by example. A child observes when an adult is polite but imitate that. Raising a child by a real example. You can’t tell a child to do not put a knife into his mouth if he sees his dad going it all the time. Etc. If you do not use your manners, you can’t ask the child to do the same. Impossible. Logical but not for him and his parents.
One day after his parents arrived his mother insulted me twice: motherfucker and bitch. Nice twice the same day. They arrived on a Wednesday and the next day it was fun. It did not react as I knew she wanted me to get angry. I won and ever since she tries to piss me off and the same with her coward husband. The insults came on October 3rd. Great.
Everything must be about them the parents. They need to take their pills, they do not feel good, have diarrhea or constipation. She has a cane but when she wants she can almost run with it. It is a way to get more pity. She is like an imaginary sick person in her head and now physically she is looking for attention. At a burger place she ate a hamburger and ate like a pig and acted as if she was gonna throw up, while people are eating at the same table of course. Nice. Always bad drama is on. She is the worst actress ever! My husband and his father too.
