How people bahave under stress

I made lesson reservations for the kids at 4pm today in the childhood learning center. therefore, we had to leave home before 3:40. I left work and arrived home at about 3:35 and this did not leave much time for preparation.

Upon arriving home, I immediately questioned maomao whether he had kept our promise to finish the handwriting practice and the sokudo exercise. Sadly, he did none of them. This made me angry and he tried to cover his lie by saying unrelated things and I just got angrier.

I yelled at him and he cried. All this did not have any effect except for delaying our departure for the lesson.

As an adult and a mother, I behaved very immature. What I should do is to deal with problems calmly. Losing temper is just a sign of incompetence.
