My husband’s sister lives with us! A few months older than me! I can't stand her! Because she is lazy! Really lazy! I never asked him to do anything! because

It is best to communicate with your husband about this kind of thing first, and suggest that he educate his sister. If he thinks this is nothing, then you can just turn a blind eye. If he also agrees with your point of view, then he will naturally tell his sister. No matter what, don't take the initiative to tell your sister, just let your husband worry about this kind of thing

I hope you will adopt it, thank you!
