The world is not at all what it seems

Understanding what really happens to a person is not very easy, but possible. You must mentally analyze what you see and hear, and at the same time take into account the circumstances in which you are. And then you can make the right conclusions. Most people see only what they think they really see.
To clarify what I mean, I will tell you a short story.

Two men are walking in the woods. They pass by a big black hole.
“And the hole seems deep,” remarks one. - Let's throw a couple of pebbles into it to check the depth.
They throw a pebble and wait. No sound.
- Wow! The hole is really deep. Let's throw in that huge rock. Oh, from him the sound will definitely be.
They throw a big stone, wait, but again there is no sound.
“I saw a railway carriage in the bushes here,” remarks one of the men. - If we throw it in the hole, then we will surely hear the sound.
They pull out a heavy carriage, push it into the hole, the carriage disappears, but no sound, still silence in response.
Suddenly, a goat rushing from nearby bushes rushing at terrible speed. It rushes between men, flies up into the air and disappears into the hole.
A farmer appears from the bushes and asks:
- Hey guys! Have you seen my goat?
- Of course, we saw! This is really forget! He rushed past us like a breeze and jumped into that hole!
“No,” the farmer shakes his head. - It was not my goat. I tied my own to a sleeping car.
