Don't tell yourself anything more than what the initial impressions report. It's been reported to you that someone is speaking badly about you. This is the report -- the report wasn't that you've been harmed. I see that my son is sick -- but not that his life is at risk. So always stay within your first impressions, and don't add to them in your head -- this way nothing can happen to you.
-- Marcus Aurelius, Meditations, 8.49
