You are correct. Thank you for holding me accountable. Sometimes I can be shortsighted, as it is human nature, and not consider the whole story. Sorry OP for coming off as a dick. I am empathetic to your situation and I hope you find some justice and your friend and her child can find a way to leave safely.
You may just have preconceived notions. I’m in a similar position and am trying not to expect this sort of behavior. However my plan is to maintain open and honest communication. If you feel resentment or animosity arising from someone, have a private meeting with them to discuss it. It’s a simple “hey I feel some resentment from you towards myself and/or other teams members and I wanted to clear the air and see if I did something to upset you?”. Usually simple, clear, concise beginnings are best. Get an understanding of why someone is acting a certain way then try to find a way to relate to their emotions. Then you can both try to come up with a way to relieve their resentment and tension between the crew members.
Another comment said “we’re all adults” but society breeds immaturity and people rarely know how to discuss their emotions so they bottle them and that can manifest as anger or passive aggression. Both of which prolong uneasy feelings for NO reason when a small discussion can usually make things better. Confrontation can be hard at first, but ultimately helps to release pressure from building up inside.
