For me, this has become a rule: thick skin and lack of emotion to criticism from people on the Internet. You became a teacher. Someone reacts very sharply to insults brought by people who are far from the real life of a person. You always remain at the level of nirvana, with the addition of good humor. My sincere congratulations and great respect. It is possible to be able to respect people from the Internet and, at the same time, not react sharply to those who try to sting.
