When I was young my friend and I were both in the same kindergarten class and it never was that important but we both had the same first name. It was fairly early in the year and for some reason our regular teacher was sick or had a training.
Chris and I had an interesting idea, we would pretend that each of us was the other. I am not sure if we fooled the substitute teacher for even an hour. We both had the tendency to answer when our whole name was given rather than just the first name.
Yup, the regular teacher was a bit disappointed, but I don’t really remember any fallout from this event. I guess being a smart alack starts young.
