When someone is rude in a public place, do you say something or try to ignore the person?

Sir [이름]^^

Good afternoon!

It\'s already Thursday!

How are you doing today?

I also feel annoyed when someone behaves badly in public.

The things that you mentioned below are really annoying.

Of course, you are a kind, polite and respectful person.

I am so blessed to have you as my student.

Have a good day.

I occasionally mutter about his/her rudeness or bad manner, but not to the level to have him/her heard clearly.

One of the most irritating thing to me is that a person throws a cigarette butt out of window of his/her car while driving.

However, it is not easy to catch them when they drive.

On the contrary, I sometimes ask myself whether I am a person who is polite, kind and respect others.

Remembering the quote in the Bible that anyone who has no sin in their life should step forward and throw the first stone, I am also a person who is entitled to criticize others.
