I understand why it is so difficult to get along with people. Based on what I understand, the way thoughts filter reality is broadly different among people. Example.
A usually focuses on quantitative details of things. Feels comfortable only when everything is neatly planned. Asks lots of questions on details and checks factual accuracy of statements. Likes odd bits of trivia.
B forgets details quickly. Focuses on the general outcome of a process rather than on details. Hates planning and imagines he will be able to figure things out on the spot (even though that's not always the case). Is satisfied with guesses and approximations rather than with detailed knowledge.

B: In [country] we drink coffee like in the states, that's very different from italian espresso or spanish cortado. We really have a different coffee culture with respect to yours.... (talks about coffee for a while)
A: Where do you usually have coffee, at home or at a restaurant/bar/cafè?
B: I don't really drink much coffee, I don't know.

A: Tomorrow is a shaving day. Unfortunately I will have to bring the razor and all the stuff.
---
B: (sipping wine)
A: So, what's the plan?
B: Sorry?
A: The plan for this evening.
B: Should there be a plan?

B: Ok, we'll meet my friends at the end of the match, when all the pople leave.
A: Where exactly will we meet your friends?

The way we filter reality is part of the definition of the self image. When another person challenges the identification between reality and the way we filter it, he is making our delusion clear to us.
That's annoying.
A: The grass is black.
B: I see it green. (Take off your fucking red glasses!)
A: But the apple is red.
B: I see it black. (Oh, fuck, am I wearing green glasses?)
So everybody would like to think that he is wearing no glasses, but turns out everybody wears glasses of some kind.
