I must confess that I was the kid that reminded the teacher about the homework
Did you really. Why did you remind the teacher about the homework?
Seriously? My bloody name was on the blackboard. It was my responsibility to remind her.
Being ambitious is often a good quality, but you must consider the costs of your actions. Although being friendly with teachers is good, being overly helpful to the point of irritating classmates is not.
I was only doing my job.
I see, and that's great you had a lot of responsibility and carried it out appropriately. Homework and schoolwork is so important to child development, so it's good you didn't give into your peers into staying silent!
