Dear Abby: This couple treats my retired husband like their personal Uber driver. I want it to stop

Dear Abby: My husband and I have friends we consider our “BFF couple.” The husband, “Brian,” recently became unemployed, which has left him more time to travel. Brian and his wife fly to see his dad in Florida several times a year. Although they live an hour closer to the airport than we do, Brian asks every time for my husband to drive them to and from the airport.
