I feel the need to explain the poll at left: "Is the thumb a finger?"
Periodically, I do what many parents who send their kids to Catholic school do: lunch duty. At some places it's called cafeteria duty, but what it boils down to is me and (usually) 2 other parents trying our best to make sure that he kids eat and then don't kill themselves in the closed-off parking lot where they play after lunch.
The last 2 times I've been in for lunch duty, one of the first grade girls has asked me, "Is the thumb a finger?" It's a question for the ages, really. You say you have 5 fingers on your hand, or maybe you have 4 fingers and a thumb.
So, I'm going back there tomorrow and I want to be able to give this kid an answer.
Please do your part for Catholic education.
