Or maybe he realized that if he hadn’t had a special occasion by then, maybe he should just wear his shoes and get some enjoyment out of them instead of saving them for some vague moment that might never come or maybe he wouldn’t even think about the shoes until after if it did.

Or he works a white collar job and had a presentation or something so it was a special occasion.
