At the risk of being a spoilsport and bringing the thread back to the original topic, I just have to say that I'm pretty sure in post #1 the OP did say she told him to stop

And again we are talking about a 4 year old asking someone their name. I guess according to some of you the mom should have brought her duct tape to put over his mouth just in case the little heathen dared to speak to the woman sitting next to him. She should have also chained his hands behind his back so he wouldn't tap on a seat that he may not have even realized that the woman could feel what he was doing.
OMG he didn't scream at her, touch her, pick his nose and fling it on her burger. He touched her purse was told to stop, he tapped his finger and asked her name. I feel sorry for those of you who think this is so appauling, it must take alot of effort to see the worst in everything a 4 year old does.
