Name recognition in Albany

Jo Ann and I were doing some last minute shopping in Borders in Albany while we were there for a meeting yesterday. The girl who checked us out asked if we were related to the Mr. St. Croix that taught math in Syracuse. We said yes and she said to tell him he would be happy to know that her math skills payed off as she is a cashier. I forget the name but she said she had him ages ago like 10 years!!!! Thought you all might appreciate the story!!!
