Isolde's idea of fun didn't have any semblance to the idea of fun Leonel had in mind.
The man's idea of fun was something along the lines of swimming near the shores, away from the giant waves, building sand castles, and getting buried under the sand.
On the contrary, Isolde's idea of fun was something along the lines of floating in the air using a parachute with a boat pulling it so fast.
During the activity, the boat was so rapid that Leonel felt like he had experienced death at least ten times. Even just watching Isolde glide on the water with a jet ski as fast as race cars pulling her made him feel like puking.
While Isolde was surfing in the big waves like a pro, Leonel was on the shore, building a sandcastle like a kid as he waited for his girlfriend to finish.
