Energy

This woman has it in spades.

I worked today as a casual teacher and was lucky that there was a performance called 'Drumbeats'.

Each child had a drum and there was much mass drumming, singing and percussion. In the wrong hands this could have led to chaos, but Angela and Rob had them fully engaged for an hour.
The energy and excitement that they had, and generated, was amazing.

The best photos show the students interacting in an enthusiastic and unselfconscious way, and we all know that's the time to snap them, but for all the usual reasons I can't show those, so you'll have to settle for a consenting adult.
