I have a friend, “Sara,” who is driving me crazy. We are both married, in our 30s, and have several children. Although we have a lot of fun together and socialize as families quite often, she has a habit of complaining about her life in a way that I find excessive. She complains she is overweight (she’s not), her kids are difficult (they’re not), her house is too small (it’s not), etc. How do I respond when she says these things? I want to be a good, empathetic friend, but this drives me nuts. Please help!
