Quick background. Sister has a child with an American guy. He has a long standing history of pretty morally indefensible behaviour towards her and her son. He’s a bully and likes the throw his weight around. He’s based in Florida (which is an extreme COVID hotspot at the moment.) As a pilot he doesn’t have to self isolate for any period of time when travelling. Anyway he insisted that he got his weeks contact last week with his son. My Sister expressed her concerns but he told her it was his right (it is.) Straight from Florida, no test, no isolation. Now I know that co parents can freely move children in the U.K. but something doesn’t sit right here, he’s coming from a hotspot area. Or AIBU?
