When Jon was about 13 years old (I was 23), I came over to Grandma & Grandpa’s house with a girlfriend, one of many that I had been dating over the past few years.  He greeted her (before I had a chance to introduce her to him), saying a little sarcastically: “hi, you must be Sue, or is it Joan, or perhaps Karen, maybe Stevie, …” while Debbie stood there rather perplexed.  I quickly jumped in saying: “Jon, this is Debbie, who’s a teacher.”  Jon smiled and said: “Oh, does that mean you have to do it over and over again, until you get it right?”
