Women are women.
They're all high maintenance, in one way or another. Either you buy them lots of stuff, spend tons of time with them, compliment them too much, or deal with oodles of bitching.
Now, there's a difference between "good" and "bad" high-maintenance. I dont mind spending tons and tons of time, and can deal with a fair amount of bitching before it bothers me. Its just finding one who you dont mind maintaining.
