Bruh, um…
Wow, I actually had to think for this one.
Does a set that contains all sets that do not contain themselves contain itself?
Well, it's not a part of that set, right? It just contains that set, so yes, it can contain itself.
If you buy a ship and over the years replace part by part until all the original parts are replaced, is it the same ship?
If a person had their body parts replaced one by one (whether it's from a donor, or it's artificial), would they still be the same person?
If you remove sand from a pile of sand grain by grain, at what point is it no longer a pile of sand?
I dunno, like at…less than 100 grains? Maybe 50?
Will senpai ever notice me?
Particle Mare will never notice you, m8. If you try hard enough, then yes, they will.
