Teens are tough to deal with. I think it's good that eldest is talking, even if it's expressing frustration and anger. Both my teens are pretty shut down right now, they chat to each other a lot and laugh together, but with me unless they are in the car (currently nowhere to go though...) they don't really talk at all. They both seem a bit depressed sometimes, which I think is kind of inevitable both when you are a teen and things are changing physically and emotionally, and when peer groups are very important but unavailable right now. It is going to be a long summer!! You seem like you're doing well staying out of the dynamic between H and eldest, keep reminding yourself that they need to work it out and that none of this (pandemic or adolescence) will last forever xx
