....it actually means their children aren't disciplined properly and are naughty?
My friend has 3 children, all very badly behaved, with no manners. She says they're "wilful". It really annoys me. She never pulls them up on their behaviour and just lets them get away with being rude to others.
For example, her 10 year old recently asked me, in front of her, if I was happy being short (I'm 5ft 4) because research had proven that short people earn less than tall people. Her 7 year old demanded the receipt for a birthday gift I gave him, because he didnt' like it. She just laughs when they behave like this and says "Awwww, she's so wilful/such a character"
Grrrrrrrrr
