A Merey can have the first impression of a bitch, but once you get to know her, she'll be an amazing friend.
This is probably because she tends to move around a lot so tries not to get too close to people too quickly.
Because of moving around she has probably seen many of the sights of the world and because she probably has old money, she has high expectations of life and probably aims to be in the performing arts (dancing, singing, acting) and is probably very good at it.
what a bitch!" "Oh no, she's a Merey!!
