My walls had chocolate and drawing over them. Drinks openly spilled on my floor and left there for some time. Climbing walls and running into glass doors...also chocolate over them and heavy painting frames being moved by 2 yr old which if fallen on this child would have killed her. Parent said nothing and worse still had no intention of leaving until I prompted it. I feel so stupid for inviting over. I feel so drained and depressed by this experience. Never has happened before to me.
