What I don't get is why you would tell me you don't get something and not have any internal curiosity as to why you don't get it. You will find in life, I think that telling people you don't get something is just like asking for an explanation. Understand that I undertook to respond to your stated lack of comprehension out of this convention even though you didn't ask a question. I don't need to be told you don't understand why I did what I did. That is a constant with me.
Well, first you are assuming the motive for pointing anything. 1 example of a different motive, is that he wants to point out a perceived flaw in your reasoning to stop you from talking. Or it could have been to make himself feel smart, or many other reasons.
There are many people who acknowledge their ignorance about something, and also don't care to learn about it. Perhaps to them, the time/effort it would take to find out the answer, is not worth the value the answer would bring.
Because people take so many shortcuts and make a lot of assumptions, you are going to misunderstand. You can believe that people have a typical motive, but you would be wrong to think you have the ability to understand everyone's motives all of the time.
