Reverie saidI see nothing wrong with utilizing astrology for this purpose, but astrology is much more complex than simply figuring out someone's Sun sign and comparing it to yours. There are several other important factors that must be considered, and you will need an accurate birth date, time, and location. If you can get all this from a guy without him thinking you're weird, then by all means, go for it.
I hope you're trolling...
Actually, no, I am not trolling. I find astrology very interesting, and I have done extensive research into it.

(In all seriousness, hey, life is weird, no harm in looking into things, but if you're taking it seriously after having looked into it, then you probably haven't looked broadly enough. For any set of beliefs there's a group that will shovel you 'evidence', but that ain't enough.
Eh, hopefully it's just a phase.)

After all, right or wrong, it's good to expose ourselves to alternative views, no? (I know I read about astrology and all sorts of such things when I was young and feel I'm the better for it.)
