Every driver on the road has a personal agenda to get in your way and piss you off.
Potty-training your toddler makes you cry because he's growing up.
You go to Burger King for a milkshake and cry like a baby when the milkshake machine isn't working. (I cried so much that the manager went to the closest Burger King to get me a milkshake.)
