While we are having a dinner at a restaurant, I remember my teacher, who give me a punishment when I’m in high school. I just suddenly share it with my friends. They think I’m weird, sharing out of nowhere. I felt ashamed of myself and after a day they have a change of heart reacting with me. It’s like our friendship fall at some point.
What should I do? Can I still go with them and ask what happened? Actually I don’t know what to do 
When I saw your post, I remembered my classmate in Grade 3, My teacher always scolded her during our Math class. It’s funny that my classmate is now a major in math. She is currently teaching at our school.
