Me and My Best Friend

This is a story of me and my bestfriend. She's been my friend since 6th grade until now. I know it's not that long but it feels like she's been my bestfriend my whole life. We've been through a lot but at the end of the day we're still friends! It's crazy because she's much closer to me than my sister. I tell all my secrets to her but I can't tell my secrets to my own sister, can you feel the same?
True friendship isn't about being inseperable, its being separated and nothing changes.
