Mandatory reporters?

All of us have noticed, at some point or another, that both the
students and adults have perpetual hickey marks on their necks and
backs. We saw this initially with the students, but have seen it on
the necks of people as we walk through the streets of China as well.
When we looked closer however, we noticed that they weren't always in
the typical hickey spot, and they sometimes formed lines. So,
being mandatory reporters as educators, we thought are they being
beaten? We learned, through questioning that Amy and David brought
up, that in pinching each other, particularly on the neck, it acts as a
cooling mechanism during the hot summer days. Sadly, during our last
massage, David endured a tool that creates these lines. They marked up
his back, trying to cool him I presume, and it was tender and sore- and
to top it off, he was charged more for this treatment!! How's that
for interesting! I'll try and get a picture of these marks later to
put up- but it's hard to be discreet when getting that close to
someone¡'s jugular.
