Astrology, why do the fire signs always have to make an a** of themselves?

First of all, nobody is perfect!!! No matter what ur sign is. There are good and bad in ALL signs!!!!!!!!!!! For example BRAD PITT is a Sagg. and he is a pretty good guy. I am a Sagg. myself and have had my vices and great ets too. We are just very adventures and very spur of the moment people. Very IMPULSIVE which gets in a world of trouble at times!!!!!!!!!!! Sometimes i wonder i am still alive!!!!!!!!!!!!! We are very FIERY indeed! Yes, we get in trouble but our lives are never a dull moment! Trust me, I KNOW!!! But all in all we are basically good people.............stay cool!!!!!!
