It has always been this way -- even with other people's children.
Long before I had a child, I went to a birthday party for one of my friend's kids. My friend's enthusiasm about this party was evident -- even after his son came up and announced, "Dad, Kelsey frowed up in the balloon thing."
("Balloon thing" = "moon bounce.") ("This kid" = "not that bright.")
My friend was also excited as he showed me the pinata he had bought for the party. One he was thrilled with because it was a "safe" pinata designed especially for small children. He actually walked me over to where the pinata was hung and explained in painstaking detail how that instead of clubbing this pinata with a stick, each child got to select and pull a string on the underside. When all of the little fingers pulled simultaneously, the bottom would drop out and it would be candy madness! -- free from errant whacks by sugar-crazed toddlers. He was so obviously delighted with this feat of engineering that he could not stop talking about it.
When it was time for the pinata, all of the kids gathered 'round, selected a string, and pulled the strings as designed. And as if it was choreographed, the force loosed the pinata from the beam on which it was secured and the pinata came crashing down on the head of a small child, knocked his glasses off onto the floor and promptly broke them.Which is when I promptly burst out laughing.
