Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
& you don't go into specifics... but perhaps your cousin likes your Mother and didn't want to get caught in the middle of things.
As people we are all viewing things from our own perspective... What you say about subtle, mocking and ignorant tones.... well those sort of things are all coming from our own perspective... there is really no way to prove what a person's "tone" was..but you are always free to stay away from the people who YOU perceive to be acting in a rude way towards you.
