At a party child opening presents Child 1 wants to see pushes past other children to get closer. Other parents are near and say no don't push to child 1 ( in a nice way like if you all stand back you can all see kind of thing) child 1 then bites hard on arm child 2- who naturally screams. ( there was no pre push shove from child 2 btw)
Parent takes child 2 away to calm down , rub arm etc and child 1 gets taken away by father. Child 1 returns still upset and still crying / shouting . Gets given cake .
Child 2 was not apologised to and parent takes child 2 over to 'make friends' again. Child 1 ignores child 2 and parents make no effort to apologise or speak to child / parent. No eye contact ( 2 parents 1 child )
Talking to the party giver it seems that the child was thought to have an austitic trait - but the parents have decided that this is not true. Whether this is relevant or not I don't know......
However AIBU in thinking this child should have apologised.
