as much as I find them annoying, I related to this story a lot where I’ve been in that position.I think you've maybe missed the point. She couldn't decide what to put back because they needed EVERYTHING in that one shop. She couldn't put the wipes back because her babies needed them. She couldn't put the nappies back because her babies needed them. She couldn't put the food back because they had obviously chosen to buy only what they really needed. That was her point.
Some people do literally have to budget for and live penny to penny, now more so than ever.
