When I got back to Phil and Kerry-anne’s this afternoon, little Grace was playing trampoline on their bed as Phil changed the sheets. She delighted in each jump, laughing and trying each time to get higher than the last.

It was fun to watch her, to peer into her world where the present is everything and the concept of tomorrow and yesterday is utterly unimportant. Where joy is jumping on Mom and Dad’s bed while clutching blanket ted and worrying about nothing, not even the risk of falling down.
