Accidentally call them Bieber.
If they're acting like that.. why would you want to tell them nicely?
Agree. If you show nice and class to these people they won't understand it anyway...
She shouldn't have to show them respect, regardless if they know what it is or not.. You don't show respect to people who give you no respect.
Get that "I'm with stupid" where there is a finger pointing and keep standing next to them.
These days its really impossible to tell someone what you think about them without offending them.
Look up the song text of "Trostpreis" its a German song but you can translate it and have a really good answer to your question :P
You must know my pathetic troll
I usually run up and nail the individual with a cow patty and yell "stupid doodoo'!
With all do respect and please don't take this the wrong way but your a full blown idiot.
It's not at all directed towards you, lol.
