Okay kiddo, so you know how there's this big store called Walmart where you can buy toys, clothes, food, and lots of other stuff? Well, sometimes people go there and they might dress or act in silly or unusual ways that make other people laugh or take pictures of them.
These pictures might get posted online, like on a website called "People of Walmart", where lots of people can see them and have fun looking at them.
But it's important to remember that everyone is different and it's not nice to make fun of people just because they dress or act differently than what we're used to seeing. It's important to be kind and respect other people, even if they are different from us.
