How the signs tell you to shut up:

Aries:	Shut up.
Taurus:	Will shove food in your mouth. If they were desperate enough to give their food away, that is.
Gemini:	I'm bored. *walks away*
Cancer:	They don't. They'd rather suffer than hurt your feelings.
Leo:	Will make whiney noises until you are silent.
Virgo:	Will make comments such as 'mmm' or 'yeah' until you realise that the conversation is going nowhere.
Libra:	Will smile at you politely whilst swearing at you inside their head.
Scorpio:	Will slap you round the face and promptly walk off.
Sagittarius:	A simple 'Nobody cares, twit,' and a kick in the shin will suffice.
Capricorn:	I have work to do. *leaves*
Aquarius:	Will stop talking altogether, eventually hoping that you'll do the same.
Pisces:	I'm sorry, but could you please be quiet...? -pause- I'M SORRY! DID I HURT YOUR FEELINGS? DO YOU NEED A HUG? *bursts into tears*
hehe, I'm a scorpio ;)
