I only pose this question having had various experiences recently with friends of dd (5-6 yrs) who IMO have been extremely rude.
We oldun's (me and dh) have just been chatting, and realised that we would have never in a million years spoken to other adults the way some of these kids do when we were kids.
For eg....
I would never have called mums by their first names, nor asked 'what's in your bag have you any sweets or drinks for us?' (then... why not?!!!)
I just feel that somehow kids have too much power, and too little respect for authority, but maybe it's just a generational thing, and our parents said similar?
I'm very interested to know what you all think.
