Today, one of my juniors is looking at his shoe, he's honestly contemplating it pretty hard. "I wish they made something so shoes stayed fresh."
Me: "Like the smell?"
Student: "What? No? They don't smell bad." He proceeds to sniff his shoe, then offers it to me and says, "Do they?"
Me: "I'm not smelling your shoe. What do you mean by fresh?"
Student: "I mean, like when your feet get hot in it, I just wish they had little fans in there."
I laugh, we go about our business. A couple minutes later he says, "Or a shoe air conditioner..."
In ten years when someone invents shoes with fans/air conditioners on the inside, it'll probably be my kid. I'm so proud.
