Okay, let me preface this by saying that nobody should ever feel ashamed of what they enjoy and are interested in, obviously we feel this a bit more deeply than most. The shame surrounding our interests from society is certainly hard to shake at times. I'm afraid this may be quite long and a bit rambly.
That said, I'm strangely taken with a delivery company in my country. I hate it as much as it brings me joy, it's the most absurd interest I've had by all accounts and definitely gets a side eye when I tell people I'm interested in the company.
I'm friendly with the blokes that work my street, and often see them out on dog walks. They know I was looking to try and work with the company, and I shared with one of them I was autistic and would need to ask about accommodations (who didn't look surprised at all, lol), and they've absolutely been enablers of this nonsense. One of the guys recently gifted me a work jacket of his that he doesn't use, and while I'm absolutely besotted with it, I still sneak it to my car and walk my dogs in it in the middle of nowhere out of fear of being clocked.
TL;DR:
I go through phases of worrying that everyone around me thinks I'm absolutely mental for my interest in a delivery company and the guys I'm friendly with are just humouring me for their own amusement, and then flip between embracing it and hoping people are being genuine. I sometimes wish I didn't have the introspective to be aware of how ridiculous I must look to others :/, ya know?
