Getting a Blue Badge is not a trophy for being unlucky. It’s a practical tool, like a good pair of shoes or a sturdy umbrella. If you think you might need one, just apply. The worst they can say is no, and the best they can say is "Congratulations, you can now park closer to the bakery."
And honestly? That’s a win worth smiling about—even if you have to do it while leaning on a shopping cart for support.
