I haven't posted in a while because some people had been saying that I was "looking for sympathy"; but I don't have anywhere else to post for advice. I do the grocery shopping; a day or two in advance, we discuss the menu for the week and what is needed (including brand names, sizes, etc.). On the day of the trip, we finalize the list and add anything we may have forgotten about. Then, because I don't drive, I usually take a taxi to the store, which is at a mall about 12 blocks away. Sometimes I may go in the mall to buy something personal, visit the ATM, etc. During the actual trip in the market, Aunty will call me several different times to add things to the list, remind me to get Brand X products, and finally, to ask what's taking me so long. When I get home, she asks to see what I bought, then complains about what I was unable to find ("I've been going to that market for years and I know that they sell it") or if I bought Brand W because our usual brand was unavailable. Occasionally I will actually overlook an item on the list because I'm rushing to get back home. How should I handle this problem?
