"Stop shouting!" I shouted. Do as I say, not as I do obviously! Then, after they have calmed down, I say "Treat each other gently"
They have witnessed a couple of 'disagreements' over the last few days, I can't help but worry it will affect their behaviour.
Treat each other gently is on my mind.
PS. As I write, they are hitting each other over the head with a balloon and laughing! No need to worry perhaps?
