Your opinion is your opinion, your perception is your perception. Do not confuse them with facts or truths. I know a certain libelous employee that needs to receive this- but I will not feed into her inflammatory remarks and falsehoods.
Keep your mouth shut in other people's circumstances and don't accuse. Only an idiot gets themselves involved in other people's issues. Don't make accusations when you don't witness. Just because someone tells you something, doesn't make it true.
