I don't have words to verbalize how it makes me feel. If it was someone else, especially a child, their is definitely going to be a scene made. I haven't had this happen in a long time, but I literally block them out and stop acknowledging their existence. edit: I'm doubling down - They want a reaction because they think you won't be able to respond back. treat them like an obnoxious younger sibling trying to get you riled up.
