If I'm your girlfriend,

-I’ll be your best friend too. You can tell me your family problems, I can give advice to them. You can joke around with me, and you can be yourself when you’re with me.
-I can also be your little or older sister. I can tease you at times, but -I will still love you no matter what.
-I can also be a strict mother to you. I may not allow you to go on gimmicks and parties sometimes, but just like a mother, I will let you explore the world by yourself because I know that after everything, you will come home to me.
-I can be the most moody girlfriend ever. I switch moods often. At times I can be the sweetest girl, and sometimes, I can be the girl. 
-I will love you faithfully. I will never trade you for anything, and when I say faithfully, it’s only you.
