Well, show me a single hobby, activity, interest, etc...in which "people" never engage in stupid behavior. People are people...which means there's ALWAYS going to be SOMEone who does something stupid, and they're the ones who get our attention, because they stick out like a sore thumb. They buy cars they can't remotely afford. They fill every nook and cranny in their house with empty "collector" tins. They own dogs they can't control. They stay out on the beach until their skin is burnt to a crisp. They ride skateboards across insane cement terrains until they fall and break their face. They keep 1000 cats in a tiny house that's about to fall over. And...they buy "cute" baby ____ (fill in blank with animal of your choice) because they're cute...then get bored with them and want to get rid of them. There's nothing to "figure out". It just...is.
