Left Right Top Bottom

I can understand someone mistaken from left to right. But this is getting riduculous. I ask them to check the top right corner, how do they manage to spell out what they see on their bottom left fro me. I just can't understand at all.

Now, we have trouble to figure out where is the top and where is the bottom then. Did the world just turned around for me, but not everybody else. I will never understand.
