3. Speakers. Everyone else is using headphones, don’t you think you should too? Yea we know your cool and a big badass because we hear your gangster rap but no one gives a damn, iPod’s come with earphones. We don’t care about your music and more importantly its annoying.
This rule also goes for people who use speakerphones instead of their handset to talk. No one wants to hear your conversation and quite frankly we’d appreciate it even more if you weren’t on the phone at all. Put the phone to your ear and cut the bullshit.
