Concept of Time

During lunch yesterday, I read a picture book about the legendary tightrope walker, Philippe Petit, to my K-1 class. It was a tightrope walk between the twin towers and took place on August 7th, 1974. Immediately after I stated the year, one of my K-1 students exclaimed, "Oh! My dad was born in 1974!"

All the other students gasped and there were chimes of the following:

"Really!?"
"What!?"
"Are you serious?"
"Oooh!!"

However, my favorite recollection is from a student saying, "No way! If he was born in 1974...then he must be eighty or something!"

According to their hypothesis, I guess that would make me seventy something =)
