You should know you are a terrible person and you should not listen to this Tom who seems to also be a horrible person. The only way you can attone for this is to wait for him to calm down and do whatever you can to be able to talk to him again, and when you do you better the the lad out every weekend until you get him laid. This "prank" you pulled could very well ruin the course of his life. Sociably and romanticly.
Again, you are scum. I wouldn't wipe my arse with you incase of infection you absolute bully.
Fix what you've done and reflect on your path in life.
