All of us have best friends. Some of us have them in school, college or at work. Others have their best friends living in the same colonies. But a few of us have our best friends living in the same house and in some cases the very same room. If you feel that your sibling is your BFF, here are 10 things you will agree with:

5. You discuss relationships and other problems.

It might be awkward initially but once you get close to them, discussing relationships and all of life's other problems becomes the easiest thing in the world.

6. You guys share everything.

When you're sharing the room, what can you not share. From the TV to clothes to the car to everything else in the house, you share with your siblings and that makes them special.
