Uh oh - somebody knows my name

Sven loves to strike up conversations with new people all the time. He generally approaches young good looking women or families with kids. Yesterday, we were waiting to start our usual Monday Greenlake Walk, and Sven was saying "hi" to a group of teenage girls, who looked like they had just finished a workout. Sven was surprised when one of them looked at him and said "hi Sven!" He looked at us in confusion. When we asked him who it was he said "I don't know." It turns out, she is the daughter of his Kindergarten teacher, and she remembered his name!
