DS1 has momentarily brought his head up from a screen.
He is annoying his siblings. He has tried playing DDs flute (cue her screaming). He has demanded that DS2 "GET OUT THE HORNBY" that ended more peacefully than I expected.
I have suggested he played the ukalaly he bought, and has never played and was told "I tried it once, I was crap." Then challenged DD to a play fight.
I've now instructed him to lay the table to keep him out of mischief.
