DD was having a tanty at a resturant the other night and a security guard just happened to be walking past. So I made the most of it and told DD that if she didn't behave the security man would have to take her away. She stopped long enough to look at him and he told her that he would leave her alone today and so she kept on with her tanty!!! Then we saw him pick up a little girl (who was lost and her poor mother was frantic in another room) so I siezed THAT moment and told DD it was because the little girl had been naughty. She behaved then
