Got called stupid for using an umbrella to keep me in the shade

Sat in the garden, minding my business having a smoke, keeping myself in the shade as the garden doesn't have any naturally and I'm not overly fond of direct sunlight, when the neighbour pops over the fence and asks why I "have an umbrella out? It's not even raining. Kids are so stupid these days."

Sir, I'm 31. And also using an umbrella for its original intention.

Edit: In addition to this, a few hours later the same neighbour is setting up a large parasol in their garden so their grandkids can stay out of the sun...
