Spring break season is quickly approaching, and many of us have long car rides looming in our future. If, like me, you plan to drive across the country with a friend, you'll discover a whole lot about that person that you never expected to know. Although being locked in a small space with someone for hours may drive you insane, you'll exit the car knowing your friend on a whole new level.

1.What they look like when they're bored.

After a few hours in the car, this expression will become the norm.

2. What their jam is.

When it comes on, you know.

3. Which song they absolutely despise.

They'll shut it off quicker than you can say "24-hour drive."

4. Every cuss word they know.Road trippers encounter numerous traffic jams and bad drivers. You'll learn your car mate's vocabulary quickly.

5. What kind of sleeper they are.

A drooler? A snorer? With any luck, they'll smash their face against the window too.

6. What kind of driver they are.

Will you be clinging to your seat for dear life or be tapping your foot impatiently?

7. The number of road trip clichés they know.

If you ask me to play license plate bingo one more time, I may lose it.

8. The extent of their singing skills (or lack thereof).

After a few hours, all inhibitors fall away and you've just gotta belt it out.
