OK this reminds me of a story I heard last year. I was co-teaching a summer school class with a woman I had never met. After being in the classroom for a few hours on the first day, the aides took the kids out to recess and she and I were getting a few things organized. Suddenly, she launches into a story about her ex-boyfriend. They lived together for over a year, traveled together, then out of the blue, he asked her to move out. She was still friends with him on Facebook and knew that he had started a new relationship just a few months later. A few months after that, he called her and asked her out for dinner. She said, "But aren't you dating someone?" He said, "Yes, she's coming too. I think the two of you would really get along." So she was curious enough to go to the restaurant. She said the new girlfriend was actually very sweet, but she still didn't quite know why she was invited to have dinner with them. At one point, she asked the girlfriend, "Do you know why he asked me to come here?" The girlfriend said, "Yeah. He wants us to be a trio!" I think different words were actually used, but you get the idea. She got up and left and never talked to them again.
I kind of stared at the woman, wanting very much to say, "Why are you telling me this?" But I just said, "Um, OK," and I went out to recess. An aide I know from another classroom came over and said, "Are you teaching with Ms. R?" I said, "Yep." She said, "She subbed for us last year. Has she told you about her ex-boyfriend yet?" I said, "Yep." The aide said, "Yeah, she tells everyone that story." We both just stood there and shook our heads. So I guess if an ex asks you out, you never know what might happen. And then you can tell everyone you meet all about it!
