Cassidy 

Cassidy is a girl who goes through a lot but doesn't want to burden other people with her problems so she keeps it all bottled up. Cassidy usually has a very bubbly personality, but will be very quite around people she doesn't know. Her parents named her after a Grateful Dead song and she never hears the end of it. She is a very loyal friend, but will fight against a friend if they turn on her. She is very hard headed and goes for what she wants in life. Cassidy can be a sporty person but would rather be at home watching Netflix. Cassidy tells it like it is, she isn't going to treat you like a baby.

Cassidy is so hard headed. I couldn't talk her out of buying a 20$ hat.
