What moment made you realize the fragility of family ties?

It feels like a stick in my throat when I talk about it. I just received a call from my aunt, saying that my family owes her 4,500 yuan and has not paid her (an old debt from about 15 years ago, but it has been paid off long ago, but she doesn’t remember it. Said we didn’t pay it back). My mother and father were confused and refused to listen to the explanation. They bombarded me on the other end of the phone and wanted to sever ties. Um. Very good, she probably forgot who gave her food, bathing, dumplings and medicine when she broke her bone (her daughter and son-in-law pointed at her at home and scolded her for ignoring her), she probably forgot who gave her the New Year's Eve gift for several years in a row. Hundreds of thousands and tens of thousands were given to her for urgent business needs, and she probably forgot who took care of her children when they were young. I have seen how fragile and heartbreaking family love is.
