My brother is a bit of a cunt, and my brother in law, and I suppose my sister is really, not forgetting my uncle Hector..... I wish I hadn't fuckin started this now.
You can choose your friends , not your family. Close the door , walk away, don't look back. You owe nobody anything here. No ties, no loyalties, no emotional debts. Your affiliations are to your partner and children..... Keep walking.
