Two Fishies

In US history Mr. Seidenstein was talking to us about college, and how he loved to research when he was a student. He said it was because he was a Virgo, and Virgo's apparently love to be obsessive about those things or something like that.
I was a definite skeptic about the whole concept of astrology, and told my coach about it when we were on that topic before. I didn't how the sun, the planets, and what not make up who we are as people. It didn't seem to make any sense because it didn't seem that those topics could be in any way related. In response to when I said this, she seemed a little upset. She told me she used to study astrology, and that I can't be a skeptic without putting some effort into researching about it. She made a good point, despite how ridiculous the whole astrology concept seemed to me. So today, I decided to look up my sign or whatever you call it. I am born on Feburary 21, which means I'm a pieces, the two little fishies. I didn't understand how someone came up with this sign as the sign for people born on Feb 20-Mar 20. I don't know how they came up with those exact dates either. What if you're born on Feb 19 11:59 in Hawaii, and then you fly over to the mainland where Feb 19 11:59 is actually Feb 20 3:59, does that make you a pieces or the sign that comes before it?
Anyway, I wanted to find out the traditional traits of a pieces to see whether those traits match my personality. According to this website, the 'astrology insight' I am supposed to be imaginitive, sensitive, compassionate, kind, selfless, unworldly, intuitive, sympathetic, an escapist, idealistic, secretive, vague, weak-willed, and easily led. Wow, that's a lot of words to descricbe me. Hm...let's see...I'm pretty sure I'm not imaginitive or intuitive, although I think I can be a little sensitive, compassionate, kind, selfless, sympathetic, and I'm definitely unworldly...Hah, I'm pretty sure I'm the most naive out of everyone I know. I'm pretty sure I'm not an escapist, even though I'm not quite sure what the exact definition is...I think I'm idealistic, or I was anyway. I am very sercretive according to my parents...Wow, and I'm definitely vague. My friends used to make fun of me because of that. In fact, someone gave me a keychain that says...'I used to be indecisive but now I'm not too sure.' Oh, and I'm pretty sure I'm weak-willed and definitely easily led because of my 'vagueness.' Hm...this profile was not 100% accurate, but it was pretty close. The accuracy could have been coincidence, but I can't conclude that unless I have a better data. Maybe one day when I have time, I'll figure out how many people 's astrology profile matches what kind of person they are.
But even though these astrology profiles happen to be accurate, I think I'll continue to be a skeptic because I don't understand how someone could come up with all of these profiles by just looking at space. But maybe I will understand the reasoning behind astrology if I do enough research...I don't know...(Ah...vagueness again...)
