In some countries it's a sign of courtship

Today when I picked Sam up from school his head was wet. Actually it was just one side of his head where he had been licked by one of his classmates. Apparently the little girl was sitting next to Sam and licked his hair, found it to be quite satisfying and went back for more. Sam, always in the mood for a good head massage, leaned his head towards her and enjoyed the tongue bath for awhile until the teacher's caught sight of what was going on and put an end to it. I showed up just moments after this event to a very wet headed, but happy, Sam. It's the special moments like this one that make raising a child with a disability so entertaining.
