I was 17. A teacher of mine was on his day off but decided to came at school and took me of my class only to go to the school cafè and talk. He noticed that i wasn’t ok at that time and wanted to let me know that I wasn’t alone, and he could help me if I needed him.
Me and this teacher had some fights before (and after) this, but to this day I am really thankful for what he did for me.
