A reminder to myself: before any prejudice and thinking of what might happen if you talk to a person... just talk to them. Try to understand what's the worst thing that could happen if you talk to them. Is it just a “no”? Or are you expecting some aggression from their side without any long-term consequences? Also think about the positive outcomes — what is the best thing that could happen if you talk to them? Is it getting a new job? Getting some support? Having a constructive conversation?
You probably need to talk to them! In most cases, it turns out that what I think about the situation with other people is completely wrong, and when I try to have a good conversation with them, I discover that I was fearing nothing. My prejudice was wrong!
The attitude you come to the conversation with affects how others would feel in that conversation. If you are open, honest and optimistic, your opponents will likely feel this. If you are full of fear, doubt, or you are ready to start a verbal battle with someone, this will not end well for sure. Therefore come to any conversation without prejudice and negative emotions.
Even if you think that you know something is true, it may not actually be. If you are preparing for a war, check your facts and make sure there is really an aggressor on the other side. Sometimes with a polite conversation you could turn your enemies into the best friends.
