Right near the entrance to the amusement park is a very, very big roller coaster, with a loop that swings all its dangling passengers around at sixty miles an hour right over the entering guests. They scream. (The riders, not the entering guests. Yet.)
Elspeth is carrying Harley on her shoulders, and buys them tickets.
Hugs. Picking up and departing the restroom. "Now we have been on all the big roller coasters," she says.
"Well, let's give your tummy some time to settle and then we'll find a little one to try."
Hugs. Wandering around parts of the park that are not roller coasters for a while.
"Okay then." They find a relatively tame roller coaster themed around ladybugs. It is not big enough to accommodate adults; Harley gets his own ladybug and Elspeth stays behind.
Elspeth has already memorized the map. There are three more cute little-kid roller coasters, themed respectively around dragons, space, and flowers. Harley may ride them all.
"Okay, we can go find some lunch for you." She rattles off the choices from the memorized map. "And after you eat, no roller coasters for a bit, we don't want you throwing up again."
There they go and there they lunch. Well, he lunches. She gets an order of fries so she doesn't stand out as conspicuously not eating.
