You couldn't blame your father. He loved you, but he was a very busy man and no matter how tired he was. You could rarely wait for the moment when he was not busy or tired enough that he did not respond to your attempts to tell you something with only nods of his head. Probably his phlegmatic personality made everything worse, or maybe you, being still a child, just took everything to heart. In any case, the fact remained that you lacked parental attention. And most of all, you suffered from a lack of neglect. He didn't have time to teach you basic things or take you to hospitals and you just prayed that you didn't have any diseases.
You went on a class tour and you felt sick. The teacher told you to call your father to take you home. The father answered only the third time. After explaining the situation to him, he mumbled and replied in a calm voice.
"Text me when you get home." It seems he didn't have time to give you a ride.
