One day morning all my classmates and I were in the mathematics class listening carefully to the teacher.
After quite a little time, the teacher went to the board to write a formula down there when accidentally a friend of mine sitting on the bench behind,
showed me a box of matches and a bunch of firecrackers which I took one of them and put the match to it and just throw it away at the end of the class at once.
It burst shortly and all the students screamed their head off and then stared at me in horror.
It was obviously clear that it was me who did that because I took action lately therefore the teacher caught me read handed and took me to the headmaster.
I was extremely afraid and quite anxious when one of the school assistant took a look at me and recognized that I'm incredibly scared thus he hold my hand and then both went to his office.
As we approached he began talking to me in order to calm me down and after a few minutes he sent me back to the class and everything went well finally.
It was such a nice experience because I found out that everything is possible to occur once but to regret permanently and besides no to be capable to make up for it.
