ignore em and if they don't like it ef em
Well, it depends. If they live with you, you have to compromise. Otherwise, f them.
That's a tough one. It can cause a lot of strife. Sometimes we can just ignore the in law. Sometimes it needs to be addressed. Meaning in as nice a way as possible, tell them to butt out. I could not come up w/a more polite way of saying it. When we were younger, my husband's dad ALWAYS had his nose in our business. Caused A LOT of unnecessary problems. Thank God he moved away and he is now occupied w/his gf. You sometimes need to be firm, but respectful as these people are your elders. It's not easy. I feel your pain and frustration.
