My mom's parents lived a state away, and once every summer we would drive to visit them. I remember this one year we were driving and I had to go to the bathroom so bad, but there weren't any rest stops for a while, so I had to hold it. By the time we got to the next one, I had to go so bad that I ran out of the car and into the nearest bathroom stall that I could. The relief when I was finally able to be was such an amazing feeling. Since then, I've learned to go whenever you get a chance, even if you don't feel like you have to go!
