What's the dumbest thing you thought as an adult that you recently learned was wrong?
I just realized while cooking that a measuring-cup cup (as measured out as 250mL in a glass measuring cup) is the same amount(s) as one of the actual plastic baking measuring cups that go inside each other like Russian dolls lol
I thought they were different somehow (something something imperial metric yadda yadda yaddda)
Your turn to come clean Lemmings!
**EDIT: to clarify, I mean volumetrically for measuring liquids

Even when you can see their eyes that isn't always the case. It depends on how sharp the angle is and where you and they are relatively speaking. You can definitely see their eyes without them seeing you.
Definitely not.
Definitely yes. I'm amazed (but not surprised) by the lack of understanding of this concept.
I suggest that everyone here play around with mirrors and learn something themselves.
I'll leave you with this. Why do mirrors work to see around corners when you are trying to not be seen?
This might help explain things.

That link shows that Mario would see your eyes in the mirror. Those light rays work in both directions. If you can see Mario's eyes, Mario's eyes can see yours. This is clearly shown in that link.
People use mirrors to covertly look around corners because the mirrors they use are smaller than their head. And if the mirror is still spotted getting a bullet in the mirror is much less lethal than getting a bullet in the head. It has nothing to do with the mirror somehow being magically invisible to whoever is around the corner.
You are wildly misunderstanding the effect at play. All this says is peoples brains are inherently misinterpreting the angles
