We have a generation slip. My granddaughter is 5 years younger than my nephew. (No Jeremy Kyle situation).
My nephew is 6 and is very rude to my parents (his grandparents and my 20+ yr old daughters' grandparents).
His mum (my sister) treats him like Buddha and talks to him like an adult.
She has asked me to have him for the weekend while they go to Paris.
A little bit of me wants to be as strict as I was 20 years ago and yet a bit thinks he is not my problem and let him stay up for hours 'because he his highly intelligent and needs to be treated like an adult'.
Do I revert to my previous strictness or let him rule my house while I swallow medication my tongue?
