I was just reading another thread, and someone commented that they call their mother by name. I remember a girl in primary school would do this too and always thought that personally, it was quiet rude, but I guess her mother was okay with it so who am I to judge.
My sister will occasionally call our parents 'mother-name' or 'papa-name', but never by their name alone.
Does anyone else find it strange or know of anyone who does this?
