I know that our storytelling can (and indeed should) be rather playful, but that does not always come naturally to me. It is certainly helpful to see how others do it. I remember in training watching Rebecca Nye as she put materials away, playfully flicking a rolled-up underlay back and forth a bit, unrolling and re-rolling it a bit. It was playful but also emphasised that we should roll those underlays back up as we put them away.
This morning, I watched David Pritchard playfully act out how heavy the merchant's bags of money were, and mop his own brow as he "struggled" to carry all the possessions across to pay for the pearl.
