First of all, yes...this sucks this is terrible as a parent and as a child to experience.
But we need to stop thinking that other kids need to be perfect. The whole idea of perfection is what going to get this world destroyed and is already destroying it.
Yes, you kid is a dwarf, sorry to say, but that chit is wierd to regular kids and they will be told that. Because kids are pure and say exactly what's on their mind with no regard towards whatever policy is in place.
People really expect perfection from 6-8 year old kids?
