The recycle symbol on the left was designed by Gary Anderson in 1970 as a single twist Möbius strip.
On the right, one corner is made, then copy, pasted, and rotated for the other two. It becomes a 3-twist Möbius strip.
My question is, are they topologically equivalent?
The locked one comes with a sim I've never heard of, which is a great start. It's also the only one you can drop the battery from. The sim looks like it's been bent in this whole time, lol.
I don't have a paperclip small enough to pop the sim trays from the other two, ugh.
Ok, pin badge that fits tells me that the SD slot on one of them is either really deep or broken, and the sim slots don't open. Maybe they need a special tool.
@Zergling_man Can't speak for everyone, but in my experience it's not about keeping the guard up. It's more about people being generally too talkative and noisy.
There's not much chitchat that I can take without getting annoyed, especially with people who are not close friends or family. And once I had to actually scream at a colleague at the office when she played loud music on the speakers (I mean, who the hell even does that? plug earphones in, it's an office, for crying out loud).
