The Mystery of Girls

During a game in which the boys were asked questions that, typically, girls would know the answers to and girls were asked questions that boys would know the answers to, the boys received this question: "During which season is it traditionally unacceptable to wear white shoes?"
"Why would it matter what color your shoes are?" Drake asked. "That's just crazy."
"That's a real thing?" Mike asked. "There's really a season when you can't wear white shoes?"
"It wouldn't be winter," Josiah stated, "because white shoes would match the white snow. That has to be allowed."
"Maybe summer," Drake suggested, "because you might step in mud and they would get dirty."
"Oh! It has to be either fall or spring because that is when it rains most and they would get the dirtiest," Josiah agreed.
"Let's go with spring," Mike suggested. "I think that is when it is the muddiest outside."
"The answer," Makenna announced, reading the back of the card in her hand, "is from Labor Day until Memorial Day."
"What?" they all sputtered together.
"That isn't a season!" Josiah shouted.
"Would that be winter?" Drake asked.
"No," Mike answered. "It's technically part of all the seasons."
"It's just traditional," I tried to explain, "to only wear white when it is warm."
"That's not a season!" Drake stated.
"I will never understand girls," Josiah said.

I kind of see their point.
