When u accidentally shout a bad word in front of others

During that time I was in 10th and studying for social science exam.

I was trying to do what others do just mug up.

But I can't mug up and I was very frustrated.

Suddenly my sir came and ask me that question.

I can't remember that question and one of my classmate told sir that sir he don't study bookback questions.

He only studies interior question.

And I instantly felt anger and shouted Muditu iru da kena 🌸 ah

Whole class was shocked .

Sir is standing near me .

The class strength was only 17 bcz it only contains some good and one who studies.

Fortunately my sir didn't take that much serious and let me freely.

Another time I finished exam and standing near door .

There are some students who are shouting a boys name bcz girls are walking in the way

That guy shouted my name.

And I again shouted Muditu poda kena 🌸 ah.

Sir is checking whether all papers are given or not on our back not too much far.

But IDK whether he listened or not.

After that I ran.

I don't use badwords commonly like my classmates.

But I can't control it when I felt anger
