One of the things I like about Japanese is the different language men and women use. It can highlight gender differences and make women appear more feminine and men more masculine.
For example, women might say いいかしら while men wouldn’t. Men might say これ、ほしいか？ while women probably wouldn’t (my friend found this out the hard way when people laughed at her).
Some of these differences are a little old and often unused in real life. E.g. young girls these days tend not to use いいわよ、そうね and so on.
It’s interesting how Japanese drama, anime, manga still use this type of language to the extreme – much more than I’ve ever seen in real life in Japan.
