I guess you fail to realize how many times you do the same thing. This is bound to happen "more often" when people's jobs entail that they communicate practically from the time they get out of bed until they go back to bed. The same thing would happen if say someone stood in place and took shots at a basketball hoop, they'll have more misses than someone who played basketball for a couple hours. I guess I am going to have to start calling you out every time I see you make a mistake. You can bet it will happen but not on the same frequency as someone whose under hot lights and have spent the whole day talking with people.
