During a visit to my best friends house the other day her 3yo DC said this (or similar)to my 3yo DC. Apparently it is a line from Kung Fu panda film? Both my DH and hers overheard this but nothing was said to the child. Now I'm not suggesting he means it or even that he is being overly threatening but I'm just not happy about my DC being spoken to like this and feel something should have been said at the time. What do you think and what, if anything, would you say if it happens again?
