We’re celebrating National Best Friends Day with 25 lessons you can only learn from a bestie.

1. Your bestie teaches you that the answer to the question, ‘Does this make me look fat?’ is always, ‘No’.
And if someone gives you a ‘yes,’ she’ll teach you how to give that person a piece of your mind.

2. Your bestie also teaches you that you are the only person who finds the question, ‘Does this make me look fat?’ an interesting topic of discussion.
Nobody cares that much but you.
