Then came a time in a particular garden in Macau – after I finished taking photos of old people doing tai chi, poinsettias dancing to the strong wind, Chinese women practicing their opera pieces and of myself, of course – when I got bored and thought that there wasn’t anything else to take pictures of.

And then I saw two people with Down syndrome walking.

One of them mischievously grabbed his companion’s butt, prompting the other to go slap-crazy. It was so cute that I followed them and tried taking pictures of them. I think they were actually aware I was following them, and they did the whole butt-grabbing/slapping around 10 more times for me to witness.
