The differences between men and women's friendships

Betty and Harold have been married for years. But one thing still puzzles (困扰) old Harold. How is it that he can leave Betty and her friend Joan sitting on the sofa, talking, go out to a ballgame, come back three and a half hours later, and they're still sitting on the sofa and talking?

What old Harold cannot understand or explain is the fact that women have so much to share.

Betty shrugs. Talk? We're friends.

Researching this matter called friendship, psychologist Lillian Rubin spent two years interviewing more than two hundred women and men. the results were completely clear: women have more friendships than men. Rubin's study shows that for emotional support a married woman is more likely to turn to a female friend.

"In general," writes Rubin in her new book, "women's friendships with each other lie on shared emotions and support, but men's relationships are marked by shared activities.”

“ Men keep their innermost(内心深处的) feelings to themselves. " Rubin writes, " Whereas(然而) a woman's closest female friend might be the first to tell her to leave a failing marriage. However, a man by society doesn’t complain about his marriage trouble. it wasn't unusual to hear a man say he didn't know his friend's marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa. "
