A couple more milestones passed! Going on a Ferris wheel after having been afraid of heights for years. “Mom, do you know how many rays there are? I’ll tell you: it’s the only time that exponentiation is commutative!”
Diving deep into the water (after being afraid to put his head underneath the water for years), swimming to the platform in the sea and diving from the platform, using a diving mask.
