Remember back in 2022 when I used to sit on our patio and basically conduct surveillance on the post office across the street? Prime entertainment. Better than Netflix, lower subscription cost.

There was one mystery that completely took over my brain for a while. Every single mail van had this weird discoloration on the roof. Looked like rust at first glance. But here is the strange part. It only showed up on one specific area. Front right section of the roof. Always. Like the vans had a coordinated skincare issue.

Naturally, I did what any reasonable person would do. I went into the post office and asked about it.

I was promptly and efficiently shooed away.

Fast forward to 2024. A crew shows up to clean all the vehicles. Redemption arc. I walk up, ask the same question again, trying to look less suspicious this time. They actually answer me. Turns out it is not rust. It is mold.

Great. One mystery solved.

Except… they had no idea why it only appears on that exact part of the roof.

The vans stayed clean for a year or so, and I moved on with my life. Or so I thought.

This morning, 5 AM, patio, filter coffee in hand, I look over and there it is again. The mold is back. Same area. Same pattern. Mail van after mail van, like they are all following the same bizarre instruction manual.

I zoomed in just to be sure. Nope, not my imagination.

For the life of me, I still cannot figure this out.
