Characters: 7-year-old boy & 7-year-old boy’s Mother
Setting: Dinner table in a Tel Aviv apartment. 7-year-old has finished eating. His mother has not
7-year-old: I’m finished. Can I go play on the computer now?
Mother: Nope. Sit with me until I’m finished. It won’t take long.
7-year-old: (ponders for a moment) How about we make a deal?
Mother: Uhum. What kind of deal?
7-year-old: If you let me go play on the computer now, I promise that when you’re old and in a wheelchair I’ll push you wherever you need to go and I’ll buy you things so you won’t have to spend your money. Okay?

I think you need to document these conversations for future reference and for the 7 year old when he becomes an adult. He will enjoy them..
Did you take the deal?
No way. Instead I suggested that when I’m in my wheelchair hopefully he will be with his own family. He didn’t like that idea & countered with: “But you’re my family!”
