I have been teaching Elementary PE for 3 years. I was telling one of my 2nd grade classes that we will be having a bowling unit. I also explained we will be learning how to keep score by hand. I explained that when I was their age that we didn't have computers at the bowling alley, we had to keep score on our own. After I had explained this, a boy raised his hand and said "Mr. Lau, that's because you didn't have electricity, right? I kind of laughed and wondered how old he thought I was.
