We had just finished a pleasant dinner at a familiar Italian restaurant, and were having a meaningless conversation over coffee after the meal. "Wasn't there a place the other day that had really good salad dressing?" "Huh? Did we go to that place?" "Eh...? Oh, right... I went there with friends." I remember there was a brief, awkward silence between us. At the time, I tried not to think about it any more, but if I had been a little braver, I'm sure I would have asked. "Did you really go with friends?"
