My best friend and I have known each other for over 17 years, and our daughters are about the same age, so they’ve always been close. She asked me to look after her 15-year-old while she went on a trip with her new man for a week. No problem at all.

But then, her daughter got really sick. I had to rush her to the hospital—she was seriously unwell, and it turned out she needed immediate surgery. I stayed by her kid’s side for three days, made sure she got the care she needed, and helped organize everything with the doctors.I kept my friend updated and called her right away, but instead of coming home early, she told me it would be too expensive to change her flight. She even said, “You don’t have to go to the hospital every day. The nurses can handle it.”When she finally came back, instead of thanking me, she yelled at me for “interfering with her parenting” and “making decisions for her daughter.” I’ll never speak to that “friend” again
