It's totally chill to raid their fridge
You know where all the best food and snacks are
You're invited to all of each others' family functions
You know the aunts, uncles, siblings, etc.
If your friend doesn't remember a memory, you get offended
How could you forget that old childhood memory we had in 7th grade?
You're brutally honest with each other
It's fine to say if an outfit looks ridiculous or if you're with the wrong guy.
You can go weeks without talking and pick up where you left
People are busy, but with best friends, you can pick up like nothing ever broke off. Best friends don't drift apart
You can show up to their house in pajamas
It's normal. There are no limits.
