a best friend is someone who will always be there for you. even when you guys are fighting about possibly being a "label" best friend. you guys know that no matter what, you will always love each other. you guys know that no matter what you're going through, or how busy you are, the other one still loves you. that's when you remember the showering together, peeing together, changing together, cooking together. pretty much, doing everything together. and telling each other everything. you guys are like personal diaries that sometimes gives you advice, sometimes just listens, and will always be your shoulder to cry on.
"I'm having such a bad day, good thing that i have my best friend to help me through it!"
"My best friend is mad at me and i hope she forgives me, because i love her so much and she is my best friend."
