One of David Robinett's greatest fears is being in a closed space.
His heart starts pounding, his palms start sweating.
Nothing makes David feel more uncomfortable than being trapped in a tight space with a lot of people.
The fear all started in college when he realized that he needed to be by the door in class. He couldn't bear being in the middle of the classroom because he felt like would get trapped by the people.
For David, being in a room without an easy access to a door makes him very nervous.
