My little nephew Sam, who was born on my 40th birthday las year, has the cutest habit of rubbing your ear when he is "getting cozy". Today I was reading him a story while were sitting on the couch. He reached back and grabbed my ear, which had an earring in it. This was an unexpected obstacle to his ear rub requirements. He had to get a better look as he searched for a good area to rub and arched his head to look at the options. Eventually he gave up and just pulled my ear as he sucked his thumb.
