Unsure who is being unreasonable here.
Family day out is planned to a country house type place. Grandparents, Uncle&Aunt, parents and their 3.5 year old all going. Plan is to meet at parents house and go from there (all couples in their own cars).
When grandparents arrive, 3.5 throws a full mug of tea all over his grandads legs/feet. Just completely random, but a real pattern of behaviour here that parents are trying to work on with their child. It hurts Grandad, tea all over carpet, everyone a bit upset. Both parents are a bit stressed.
Child refuses to apologise for bad behaviour. One parent then decided that they are not going on the day out. Working on consequences of actions with child at the moment - bad behaviour, no apology, day out with family cancelled.
Grandparents and Uncle&Aunt don’t undermine parents and although are sad they go on their way to the day out. When they’ve left - other parent goes mad. Thinks it’s complete overreaction, thinks won’t impact child’s behaviour, ruined a day out for the whole family over what they consider a small incident.
Now caused massive disagreement within the family. Who was in the right? Was this an overreaction?
