There is actually a big difference in appearance between the two people. Elizabeth is recognized as a beauty, and Jane Eyre is plain. Although it is not pleasant to say, appearance can still affect a person's personality.
Before meeting the hero, they had different life centers. One is a lively girl in the boudoir, and the other is a governess who needs to earn money by herself. The things you hate are different, and the communication environment is different. I can't imagine Jane Eyre and Mrs. So-and-so discussing topics such as skirt lace dance, and the resulting personality image is naturally very different. In fact, from pride and prejudice, we can see that Elizabeth is quite idealistic in many cases. After all, she is a chicken under the protection of her parents. Jane loves to see things, and sometimes she is pessimistic because she sees too much reality.
The social status of two people is actually different, I mean at the beginning. One is the daughter of the squire, and the other is a governess. At that time, the status of governess was not high, so although the heroine in both books emphasized that she was equal to the hero, I always felt that Elizabeth was more emboldened. But later, after Jane Eyre inherited the inheritance, it was another matter. At that time, Mr. Rochester was not so attractive. Think about their reaction when they meet women with higher status. Elizabeth is bolder.
That's all I can think of.
