What turned me away from Ron was not his constant talk about how great he was, I really didn't care. I don't care about his test scores either and never paid any attention. What caused me to distrust him was to hear him talk poorly about others and then hear through the grapevine that he was saying similar things about me. I used to think to myself "what did I ever do to him?" which was absolutely nothing. My advice: forget about him and move on.
