The unknown should fear me. For I adapt quickly to many and most situations.
I don't fear a salesman. Their shallow minds bore me. I have nothing they want beside money I'm short on and they offer nothing to me short of theft.
I will do a little homework on a topic to ensure I know what I am getting into, and to make sure that those involved take me...semi seriously.
Oh yes....unless there's travel involved.....that's always worth the unusual risks.
