being polite when text messaging: no spamming, be short, go easy on capitals, be personal. watch for double meanings (is LOL "laugh out loud" or "lots of love"? could get you punched in the nose!) and no text overload or you might move onto the world of "textual harassment".
Right textiquette: ILU! CU l8tr!
Wrong textiquette: I love you I love you I love you please see me OMG I think we should be 2gether. Did you get this text? Call me! LU! LOL! IXXXXXU!
