She's married to DH's brother. They got married last summer after about 2 years of dating. They live next door to MIL while we live in different city. We go visit and stay with MIL during holidays or whenever we can (She's getting quite ill) SIL and her husband would come over for dinner (I cook 90% of the time) I don't mind cooking and preparing food but she has never ever offer to help or even cook one single meal. She would stay at her place until everything is already prepped then casually ask me if there's anything she can do to help. I just get so frustrated with her. she never cleans up after even though she promised she would.
Same thing happened today. She told us not to do the dishes because she would come do it first thing in the morning. She finally came over around 4.5pm and obviously someone else already tidy up the kitchen. I asked her... oh I thought you said you were coming to clean in the morning then she told me"oh yeah but I slept instead"
Can someone tell me what kind of response is that? It just gets really frustrated because it's really not our responsibility to take care and look after her especially when we are just visiting. She is 36 and older than me.
The whole family know she's lazy and her little tricks when it comes to avoid housework. But I refuse to let her ruin my quality time with the family. Should I confront her or should I just ignore her? Help!
