When Sister expressed an interest in driving, I directed her to the school - to the very instructor that I had. He was so good and put me at ease so much that I told her he was the only one she should learn from.
Today she had a lesson and when he was due to pick her up, she told me I should come out and say hello. I refused because there was no way he would remember me. After the lesson was over, she came in the house and told me that he asked how I was doing out of the blue. She told him that I had moved but was here now, and relayed the dialogue we had had about him. He told her to tell me that he wasn't leaving until I came out and said hello to him. So I did. He was like, "Why did you think I wouldn't remember you?" and I said, "Um, because it's been three years?" He laughed and said, "I remember all of my students." And he asked about Texas and how my driving was. Weird.
