The teacher thought for a while and answered:
Let me give you an example
Two men come to me, one clean and the other dirty I offer them
I take a bath.
Which one do you think will do this ?!
Both students answered in the same language: Well, of course, dirty man!
The teacher said: No, clean man! , Because he is accustomed to bathing and the dirty man appreciated
Does not know it,
So who bathes?
Now the boys say: Clean man!
The teacher replied: No, dirty man, because he needs a bath!
And he asked: Well, then which of my guests are taking a bath?
Once again the students said: Dirty man ?!
The teacher said again: No, of course both! , A clean man is accustomed to the bath and
A dirty man needs a bath.
Well, when will he finally take a bath?
The children replied in bewilderment: Both!
The teacher explains again:
No, none! , Because the dirty man to the bathroom
He is not used to it and a clean man does not need to take a bath!
The students protested:
Yes it is true, but how can we tell? , Every time you say something and every time it is true!
The teacher replied:
Well then you see, that's logic
And from everyone's point of view is different!
