A listener writes: Each year, a friend invites me and my husband to his New Year's party. This year, we're expecting his invitation but haven't been contacted yet. Meanwhile, another friend, who also knows my first friend, invited us to her New Year's celebration. I prefer to attend the usual party that I'm assuming we'll be invited to, but don't want to hurt feelings when sending regrets to the one I was, technically, invited to first. How do I decline without explaining where I expect to be going?
