Why do people copy others?

[Maria]

I think people copy others because they are afraid to be themselves as they are scared of not being accepted. People who are unique and themselves tend to be called weird because they don't fit in with everybody else which is what I reeeally hate. Why can't people be themselves and stop imitating the world? We would have more of a variety of people in this world if people were unique and themselves, and more people would be accepted into friendships and jobs etc. because there wouldn't be an inunique (if that's a word) expectation to live up to ('be like everyone else'). If more people were unique, more talents would be discovered.

I'm bad at explaining things but what do you think?
