How to remind grandpa not to love cleanliness?

It's really annoying that my father-in-law doesn't pay attention to hygiene and wash his hands.

Briefly introduce the situation. I have no mother-in-law, only my father-in-law. Since last year, my father-in-law has lived with us (before he was in his hometown in the countryside, we were in other places), and then he has been here for almost a year. I said it doesn't matter. I can help look after the children. I can earn living expenses when I go to work, but people say that he won't take his children to the kindergarten to pick him up, so I still take them at home.

Sometimes it's embarrassing when a husband leaves his job? Some questions are really unacceptable to me. Some people may call me melodramatic, but I think there will be problems, such as not closing the door when going to the toilet, not flushing when going to the toilet, not washing my hands after going to the toilet and then coming out to get things from the kitchen? In other words, you can turn over a dish when you eat, and you don't know what to pick.

Even if we are junior, we should respect them. After dinner, we used chopsticks as toothpicks, and I almost collapsed. We went out to play cards and didn't come to dinner, so we had to call. Sometimes I talk to my husband, and they say he just needs to pee. There are too many similar things. What would the sisters do if it were you? Give some advice!
