What would you say?

After receiving the beautiful tulips the other day from a sweet, sweet friend I came home and hooked them up w/ the proper environment to thrive for as long as possible(i do have better luck w/ flowers then fish). Never missing an opportunity to have a valid excuse to ask a question, or just to hear his own voice, Joey asked me why I was putting them in water. And, as simply as I could, I attempted to explain my understanding of why that's what we do. I told him that flowers had to eat and drink just like us so they didn't die, but instead of having a mouth like we do, they used their stem like a straw and sucked the water up to the flower, and that's how they stayed alive. That only prompted 4,000 follow-up questions and after realizing that maybe a better answer would have been a simple, "because," somehow the attention was redirected and it was dropped. Tonight, he came home after spending the weekend with daddy, and guess what the first thing is that catches his eye? Yup...the sucking stem straw of the dying tulips. So, this is JOey, "watching the water go up, I see it, the flower is really thirsty mom, really..." NEver a dull moment...
