They don't seem too distraught to me.
So, you know every emotion, history, and soul of these children?
I knew kids from the house next to me who would smile at me and wave.
We later learned their father was so abusive he would take their little hands and hold them under hot water as punishment. He was later arrested.
A greater argument can logically be made that after 2+ weeks out of that abusive atmosphere, the children are on the road to being children again.
