The scene is dinnertime.
Me: "Just think, one month from now Trevor will be in Italy!"
Evan: "Yeah, and 90 years from now he'll be dead!"
(To which Trevor responded, rightly enough, that we can't know that for sure. People do live to be 110. Of course, then it was pointed out that what we can know for sure is that 90 years from now I'll be dead. Thank you, dear children. I am so glad those math and biology lessons did not go to waste.)
