How do you respond when somebody you have never met in person and only exchanged a sentence or two with online suddenly tells you they are "honest?"
People who can be trusted don't demand to be trusted.
I get this same feeling when Trump or any other politician or sales man says any of the following;
"Trust me!" .... ummm why should I do that?
"I'll be honest!" .... Normally, you aren't honest?
"I won't lie." .... Normally you are lying?
"Truth be told." ... What were you telling before?
