I have noticed that a lot of things that are borderline mean is considered okay to say or do to siblings while it is not considered appropriate to do to anyone else. Have any of you noticed this or is it just me? Can anyone explain this weird phenomenon?
For example it is considered normal for a dc to call her sibling greedy when she gets extra food while if said dc said the same thing in a similar situation to a friend, the dc would likely get told off.
