My greatest shortcoming is that I"m not a fast thinker anymore. I don't like going into these conversations, I'm not sure I defend myself well speaking, I tend to listen more than speak, and let the "currents" of the conversation direct my answers.
I can totally sympathize with you on this one. I am not as quick and sharp as I used to be even though my wisdom has increased overall. I am also more accustomed to typing than talking now that the information age is fully upon us.
This is why doing what you are doing is a good thing. Not only is the additional communication experience a good thing just for practice and repetition's sake,but when you can sit down and talk to some of these people it helps to limit any intimidation factor that might be laying dormantwithin you.
It can be tough to have to deal with law enforcement situations when you are on the street and the subject of possible negative actions. It can be intimidating. I know it is for me especially if I am not quick with my wit that day. Going in to talk with people at least provides you with a more comfortable atmosphere than what a spontaneous public contact may offer when you are being subjected to some sort of investigative inquisition.
