Someone who's always there when you need to be picked up, someone who can joke, be mean to you and insult you but still love you and cherish you at the end of the day, someone who will always be embarrassed with you but someone who will also embarrass you. Someone who's like a sibling but also your advisor to make sure you don't do anything stupid. Overall, someone who's kind, caring and supportive but isn't afraid to poke a bit of fun at you.
