Just falling from my head...

Robin and Dallas are playing together and I turn to look at what they are doing and Dallas is trailing behind Robin with a string hanging from his mouth and Robin has a hold of the other end leading him along like a horse. Robin previously had the metal spring to a wooden clothes pin stuck onto the end of this string so I said to him "I don't want any metal put in Dallas' mouth so if that's what he has in his mouth please take it off" Robin replies "No Mama, it's just string and IF he did have metal in his mouth and IF he died he could just be a fossil instead, but it's just string.".
