A recent conversation with my son about his not-quite-3-year old sister.
"Mom, come here." (said urgently) "Sit down. I need to talk with you. It's important."
"Sure, hon. (concerned Mom...) What's going on?"
"It's about my sister. I think that in the future, when she does something good - you should think about giving her money."
"Okay...why?"
"Well, I went in her room today. And she has no bank. No nothing. She's BROKE, Mom. BROKE!"
Later I went in to find that my son had taken some of his savings (about $.78, mostly pennies) and put it on his sister's dresser. After seeing this - I went out and got her a little bank. Not sure what my son thinks that his sister is going to do with this money - but couldn't resist supporting his "cause."
