When perceived this way, they fail to realize that the best kind of friends are the siblings you grow up with. Many friends believe that dating your younger brother is not cool, they refuse to understand that a younger brother defines who you are and can actually be a great friend. A sibling who gets on your nerves, embarrasses you, steals your things, and someone you constantly argue with can actually be a big part of who you are and who you will become. My sister can be annoying sometimes, but that doesn't change her vital importance to me. She has developed into more than just my little sister who I fight with, but someone who contributes to who I am and has more meaning than just my little sister. Even though my sister is perceived as a nerd or someone I will never get along with, she is actually someone who means more to me than anyone else in the world. She has had a bigger impact on my life than any friend I will ever have and that gives me a great reason to celebrate her as my own
