Barn Drama - that is what this is. People get hurt with barn drama. I wonder if our horses can pick up this tension and grief caused by how we treat each other. We owe it to our horses to treat each other as we would treat our own horses - with love, respect, and honor.
I am no expert, but here is my take: As in horses, with humans there are always reasons for behavior - usually the reasons come from places of hurt and sadness. If you feel you are able, try to talk to her with an open mind and open heart. Maybe you are projecting things that are not accurate. I have done that before - thought someone was rude when they were really not feeling well or they were just in a hurry. Tell her how you feel - it may end up in a valuable experience for you - OR NOT - Know this: it may end up terrible. If she is truly wrapped up in a world of stress and anger, you may be the target of that if you approach her. If that occurs, keep yourself emotionally safe and control your actions (maybe bit your tongue and pack your things). Either way, talking to her would give you answers. Only you can decide what you want to do. Keep us posted. Good luck - and thanks for the discussion!
