Okay, this has been pissing me off for several weeks now. It's grating on my nerves. So, I drew a little illustration to explain my situation:
Excuse me, sir Blue Pyro, don't you think you're being a little rude to mister Red Scout?
Red Scout has music too, he has his headphones on, but he is listening to much quieter music.
Red Scout likes his music. He sees that you like your music, but you're listening to yours so loud that it is disturbing Red Scout.
So, sir Blue Pyro, why don't you turn that music down? Or get bigger, noise-cancelling headphones if you like your music so loud?
Those little ear buds are blasting so loud that Red Scout could sing along to your music if he wanted.
This goes doubly for when you're in the computer lab! Red Scout wants to do his work, not listen to Prodigy! (I like Prodigy, by the way.) You couldn't be more rude to mister Red Scout if you played episodes of Glee on the projector!
(What gets me the most about people like this, is that they have NO CLUE how rude they're being. Not only that, but they ALL own teeny-tiny fucking earbuds that somehow seem to broadcast their music to the rest of the room.)
