The spread of bad manners among people, making a lot of people think that it is normal, but everyone has a duty to bear these bad behaviors, be you as you want others to be, deal with others with your morals, your origin, and your upbringing, and avoid those with bad behaviors so that the matter does not affect your psychological safety.
Treat yourself well and avoid getting your tongue from others, whether with sarcasm or criticism. Promise yourself to live from today, maintaining your inner peace by avoiding these harmful people.
And if these people are close, try to narrow the deal as much as possible to avoid further harm.
