As the chief group of my characters still runs around without very clear shape I will focus on the protagonist of my current story.
She used to have various nicknames, from totally neutral ones to malicious.
She was called a tomboy because instead of playing house she was more interested in building one upon a tree.
She was called bookworm because she loved to read, and read nearly every book in school library.
She was called a nerd because she was very dedicated to her studies.
She was called mental case because she used to see things no other person could.
She was called a weirdo because she was always a little different from her peers.
She was called a wicked witch because she kept a very unusual pet – a crow.
