Out of line joke
Way back when I was in school we had some sort of class activity wherein we would right our names on a paper and pass it along, the students who receives that paper will have to write the 1 thing that you see or like about that person then pass it along to the next student..
Me, not thinking clearly, wrote "pokpok" as a joke on one of the students paper.. it was a disaster, it made her cry and it became talk of the class.. I was so afraid to admit it was me and so embarassed of what I did. I was so ashamed, I wanted to apologize and clear things up but never did find the courage to do so... years passed and I haven't admitted it to anyone and I still carry that burden and always regretted it...
I know that was an asshole move.. sorry for being a coward and making jokes that is certainly out of line...
