You are what you eat

This little one has a cold.  His nose is running faster than an Olympic gold medalist.  Today, while we were having lunch at Subway, his nose started to drip.  Before I could dig in my purse for a tissue, he took the bread off his sandwich and wiped his nose with it.  Afterwards, he reassembled his sandwich and ate it like nothing ever happened.  For some reason, I let him do it.  I guess I figured that the snot came from his body and it probably wouldn't hurt him to put it back in his body.  I just threw up a little in my mouth thinking about it.  It is true that you are what you eat, because this one has been an absolute booger ever since.  At least he's resourceful. *sigh*
