Not everyone is lucky enough to find a best friend. But if you do, it is the best thing in the world. People constantly ask if the two of you are sisters, and most of the time you just say yes. You tend to describe this person as your ‘soul mate’ or ‘other half’, and you can’t imagine a life without them.

This person seems more like a sister to you than a best friend, and you truly believe that somehow the two of you were separated at birth. When your best friend is practically your sister, it's pretty clear.

1. They call your parents mom and dad.

2. They don’t knock when they walk into your house…

3. …and they eat all your food without asking.

4. They come over just to take a nap.

5. They know anything and everything about your family…

6. …and your family knows anything and everything about them.

7. Family vacations feel wrong when they aren’t around.

8. You don’t have to be home for them to come over.

9. They have their own room in your house, or at least their own bed, in case they decide to have an impromptu sleepover.

10. Your parents like them more than they like you.

Thank you to all my ‘sisters’ out there, for being the best friends a girl could ask for. <3
