Abuse? I'll take the downvotes on this one, but if a 13 year old said that to my wife and she slapped him or dragged him by the arm back to his house then I see that as entirely appropriate.

Now, OP obviously was speaking in ignorance, and if the kid realizes his mistake and starts screaming apologies then, yea, take it easy. But I'm gonna go out on a limb and say most 13 year olds would know what they are saying there...and they deserve to get smacked.

EDIT: Actually, on second thought, let me say "appropriate" may not be the right word. Instead I'll say I think it's "understandable" if the 13 year old gets slapped, etc for a comment like that.
