Walking with your arms folded

Do you do it?

It just seems so weird and unnatural to me (if I was to try it, and also seeing anyone else do it).

I know reasons for crossing your arms might include warmth, or comfort or even as a sub-consciously defensive posture but I just saw two friends walking along chatting happily side by side so it was apparently out of choice. And folding your arms while seated or stood still is very different to jusy walking along the street 🙃

I just notice weird things like this, like a man with camo trousers on but also a high-vis vest. Does he want to be seen, or not?? 🤣
