From my experience, men and women talk almost the same amount, but women are able to talk a lot more about a lot less. My flatmates are able to sit and talk for hours about neutral colours and the the best type of heels to wear with which type of dress, and when they cover every possible option they just loop back to the beginning and run through them again. It's mind-numbing, but I guess it's just because I'm not interested in it. To them, the things I talk about are probably a lot less interesting too.
