We've all experienced what it's like to have a best friend. That person you're so scary close with that it doesn't even occur to you that there may be things about you that they don't know. This week, I decided to test this theory with a person who knows me like nobody else: my best friend, Marisa. To conduct this experiment, we decided to compile 50 questions by borrowing from different websites and making some up ourselves. I first took the quiz for myself, then posed the questions to Marisa, noting her response. Her responses to the questions are seen here, followed by the correct answer. I then gave her a score of number correct out of 50. Feel free to take our version of the quiz with your best friends, family, or boyfriends and girlfriends. Do they really know you as well as you think they do? Let's find out.

1-12 out of 50: You call yourselves best friends?!

Well, crap. If you're reading this, you have some serious teaching to do. Your BFF or significant other is basically clueless about you. Take the time to sit down and get to know each other! This is just embarrassing.

13-25 out of 50: Still Not So Hot.

Aw, your friendship is most likely new, and that's great! This a good place to be at, because hopefully the confusion about one another is relatively mutual. Hey, it could be worse. But your best friend definitely has some shaping up to do if they're going to pass this quiz the next time.

26-38 out of 50: Almost There...

Hey, congratulations. You're almost on your way to being inseparable. There are some facts about your BFF that you could stand to brush up on, but you know your other half pretty well. Keep up the good work!

39-50 out of 50: Extremely Loud and Incredibly Close.

Damn. Nothing gets by you. You know your best friend like the back of your hand. Congrats on making it to the much-coveted "farting in front of each other and finishing each other's sentences" stage. Now go share a pint of ice cream and dance embarrassingly poorly in public, you deserve it.

Marisa's Score: 34 - Well, this is awkward...

Share this quiz with your best friends and see how well you do!
