What's so funny about onions?

Recently, Miss A had to help me prepare broccoli salad for the Girl Scout cookout honoring dads later that evening. (She is so much like me in so many ways and lacks in the cooking department as I do. Miss M on the otherhand loves to help in the kitchen.) I was showing her how to cut the red onion and lit a candle to help with the fumes. (Try it; it really does work!) She went and got her recorder to play sad music befitting the occasion.

Then, I when I cut it in half, she wanted to count the rings to see how old it was. After that, I was explaining that I first cut across the half one way, then the other, perpendicular to the first. "Oh, like latitude and longitude!" she stated. Didn't I tell you this girl was smart?
