If a guess of one family member has a conflict with another family member but behaves generally in a civilized way, talking to other people. As soon as a small altercation occurs, that guest is told to that he's not welcome and to get out of the house while a group of people walking towards him pushing him to the door not even allowing him to pick up their coat from a room (the host went to get it).
AIBU to think that it's very exagerrated? What WOULD justify this reaction? A physical fight?
