Not parenting but
Niece is 8, a nice girl who comes round once a week
However if I ask her a question the chances are I will get a stupid answer of her. Like today I know she went to town to change a toy that was broken. What sort of toy was it I ask her, response, don't know, which shop did you buy buy it from, response, factory - no such shop exists under that name locally.
It is always like that.
How do I respond to her? if it was my DD I would go mad if she treated people like that, sister defends her.
