Be A Nice Girl!

OK, this should go without saying, but being catty and malicious doesn't do anyone any good. Not only is it unbecoming, but as Justin Timberlake says, "What goes around…comes back around." So next time someone offers you the chance to write in a Burn Book (or do something equally as nasty), think about Mean Girls and the big mess that being cruel got Cady (Lindsay Lohan) in. Besides, hotties like Aaron Samuels (Jonathan Bennett) so don't dig beeyatches.

You Say!
