My 16 year old daughter is ill with cancer.
Yes this is difficult for her, as it is for all of us.
But she is also a typical 16 year old girl, and sometimes this means she has lip and sometimes can be a bit of an idiot.
Therefore I will tell her off.
She says this is unfair, as she is ill, and I say no as she's being rude, and illness doesn't allow her to be rude.
DH says I can't tell her off when she's ill.
AIBU to think I can't live for possibly months with a rude obnoxious teenager (admitedly not all of the time) that is beyond repremand?
