Can you think outside the concept?

A Wisconsin student was sent home from school for wearing shorts. The Principal said the shorts were not appropriate for winter weather. My first thought was, “Are they sending the girls home if they’re wearing a dress?”
Chances are, he’s going from a warm house, straight to a warm car or bus, then straight into a warm building. The chances that he’ll actually have to brave the “elements” for more than a few minutes are slim. Further, I’d bet that not one of the students is dressed to withstand the weather for more than that. Are kids wearing t-shirts? Probably. What’s the difference between wearing something that exposes your arms and something that exposes your legs? Are some kids wearing shoes that are worthless for withstanding the weather? Probably.

However, they won’t be sent home for wearing Tshirts or heels, only for wearing shorts because shorts=summer. Like bacon and eggs=breakfast food.

What have your experiences been with people who can’t seem to get around “that’s just the way it’s done,” and don’t think it any further than that?
