Does it piss you off when people are rude for no reason in particular?

Broadly speaking, with the exception of those who are clinically insane, things are said or done for a variety of reasons rather than “… for no reason in particular”.

“Rudeness” is not really an objective characteristic of personality. It is a derogatory, and very subjective, judgement made by someone who takes it upon themselves to criticize another person’s interaction with them (or others), often with the intention of imposing a measure of restrictive control, or in an attempt to acquire a degree of social superiority, over them.

Example 1: The parent blethers on incessantly about something, and if the child attempts to say anything whatsoever (relevant or otherwise). The parent raises his voice saying: “Don’t you interrupt me when I am speaking! I can’t abide that sort of rudeness.”

The parent is clearly trying to exercise a control, over the child, oblivious to the fact that: if “interrupting” is indeed rude, he is himself being just as rude by interrupting the child, and by his own example, further training the child to do likewise in future.

Example 2: Individual A says: “That’s bullsh!t” Individual B retorts “Don’t be so rude! It pisses me of when you use foul language for no reason in particular.”

….. garnering for herself a grandiose exemption from the social niceties that censure “rudeness”, by using the taboo phrase: “It pisses me off”, herself.

We can all be rude when we feel like it can’t we?
At least, we can when we have a reason to do so.
