They are your best friend. Someone who is always there for you and makes a difference in your life. Someone who you became close with really fast. You can talk to them about anything and they always give the best advice and will always be able to help. You learn alot from them. Usually older than you, but not by much. They truly care!! <3
My kuAu!! Love that girrl, she always know what to say!!
