Washington (ANI): Actress Lucy Liu feels that a recent change in the outlook of women has mystified men on how to deal with fairer sex. The Charlie's Angels star admits it has become harder than ever for men to predict the best way to approach a woman. "I think men are in some ways a little bit confused but I don't mean that in a bad way," Contactmusic quoted her as saying. "There was a time when they were expected to open the door for a woman and pay for dinner and do all of those things. Now they don't really know what to do. They don't want to be chastised for not opening a door, but at the same time, some women are happy to open a door themselves," she added. "It's not something men appreciate or expect."."
