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

    mirror/reflection

    Yep, that’ll do it, altho its weird he didn’t see her. Mirrors reflections are usually bidirectional, no? Like if I see you <-> you see me usually…

      You get used to seeing something your whole life and it becomes background noise, but it wouldn’t have been like that for the mom’s whole life, she’d be more likely to notice that she can see him that way.

          The reflection is only bidirectional if you can see the other person’s eyes.

          It’s like if someone is in a bathroom stall. You could see the stall is occupied by seeing their feet stick below the wall of the stall, but they cannot necessarily see any part of you since their eyes are not where their feet are.

          Same principle applies to reflections, where maybe the body part that you can see is just the top of the head, and since the person isn’t tall enough they can’t see that you can see them.

            If you can see their eyes, they can see your eyes. But it’s possible you can see some of them without them being able to see you, or the other way around. Unless your eyes are the only part of you (because you’re a camera), you need more information in order to know they can’t see you.

                  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
