Kids are so expensive these days

I have a vivid memory of my parents saying this when we were younger. They always added the phrase, "and that doesn't even include the cost of ketchup." Other adults would laugh, but I never understood that....until now. Callie was eating her french fries, when all of a sudden she holds her fry out and says, "Dip, dip." I thought this would be quite cute, so I put some ketchup on her tray. Impressively, Callie was able to eat an entire mound of ketchup and just one french fry. I think I'm beginning to understand what my parents meant!
