When this woman is upset with her SIL and brother, she asks Reddit:
I have never gotten along with my SIL. I find her to be lazy, selfish, loud and demanding. The only good thing about her are my three nephews (ages 5 to 12).
My brother and SIL are flat broke from their various business ventures and are really struggling. I've stepped up many times with financial assistance. For example, I'm the one who paid for my nephews' extracurricular activities.
Recently, their financial situation got so bad that they can barely afford groceries. They were literally splitting peanut butter and jelly sandwiches.
That was unacceptable and I offered to buy them weekly groceries. They accepted my help.
I don't do online grocery shopping because most of the time they get the order wrong or don't have what I want. So I just go to the store. I'd get an email from my bro or SIL asking for stuff. I'd buy their groceries with mine and then drop their stuff off.
