Why do you feel the need to laugh like hyena's on the 630 am train? We don't care what is so freaking funny and are just trying to peacefully read a book or take a nap. Please shut the heck up and laugh like a normal person without waking up the entire train. Every word out of your mouth does not have to be 1000000 decibals above normal.
Sincerely,
A really annoyed train rider who has been dealing with your loud screeching voice for the past 2 years.
