i have just discovered that i am not in fact a libra, but am a virgo. yay! that libra sign never made much sense to me anyhow. apparently astrologists are behind the times and that due to "precession" the place in the earths sky that we see constellations has altered 36 degrees to the west. thereby placing the astrological constellation, the virgo, in the nights sky on my birth, and not the libra. after reading the write up on my new sign, it all makes so much more sense. i don't run my life by the zodiac, but it's interesting nonetheless.
oh, and the phrase "hoist with his own petard" comes from the time of the stuarts and is when an invention that was used to blow open gates blows you (the bearer of said device) open instead.
