The Apple and the Tree

Yesterday my eight-year-old and I had the following conversation:

John: "Dad, do you know a lot about computers?"
Dad: "I know my share."

John: "But do you really know a lot?"
Dad: "I know pretty much."

John: "What buttons to you press to make that come up (pointing to the Start button)?"
Dad: "Ctrl+Esc"

John: "And how to you make it do Run?"
Dad: "Ctrl+Esc+R"

John: "Cool."

Cool indeed. : )
