I will try to explain at the most primitive level possible, although I perfectly understand that even at this level, you may not be able to understand me.
And so an example:
Suppose you are busy with some painstaking and demanding work. You do it, and from the side above you or behind you there is a person standing and watching this, this person does not even bother you, he is just silent.But one fine moment everything starts to fall out of your hands and the work does not stick and you have nothing does not work. But as soon as this person leaves, everything immediately turns out well for you and you quickly finish your work perfectly.
