This is quite great not the fact that you have bumpers sir (everyone does) but the fact that you were humble enough to recognize them and are willing to work on it, I envy that sir. Well my bumper is pride, i like to always think of myself mentally above other because I'm a deep thinker and I analyze things from different perspectives. So most times I just sit in pride, wait for others to make all unnecessary suggestions and just at the edge bring in my response and pride in my acculades.
