Four is a great age. It's an age of discovery and questions. Fortunately, when you're four, your mother knows EVERYTHING. She has all of the answers, and saying "I don't know" is like pulling the rug out from under those four year-old feet. (And usually results in some kind of emotional melt-down.)
When my son asked me where the hot water came from, I showed him our hot water heater. Easy, right? Then he asked me where the cold water comes from. Well, I don't know where the cold water comes from. I told him it came out of the pipes that way. Which, by the way he did not buy at all.
I'm a writer. I like to think I have a great imagination. But I also like to tell him how things are. So while I could have told him that the cold water came from the city under the house manned by small earthen creatures, I just endured the meltdown.
Has your child ever asked you a question you couldn't answer? And can somebody PLEASE tell me where cold water comes from? (Real and imaginary answers are welcome.)
