I have felt this same way so many times. The relief of getting back to your domain (your seat) and knowing you don't have to do that for a while is amazing. Then you feel it...that inconveniently timed urge to pee...and it all starts again.
happens too often. Most of the time I stay quiet because 1. I'm not admitting that I am quiet, because I'm really not, I just don't know you 2. Some unintelligent thing will come out of my mouth if I open it and 3. What's the point in telling them why I'm quiet when they wouldn't understand or care or stick around long enough anyways
