‘I watched Arna immediately go to defend herself and said ‘buutt mummmm he—-‘ she started to get upset.
‘I said ‘Arna ..’ her face dropped … Jax continued to cry … and I said “Arna, you said stop. He didn’t stop.
“You did NOTHING wrong. You stood up for yourself, and you will NEVER get in trouble for that”. I watched her face go from frustrated to still and content.
