Staying Cool on a Hot Day

"What next, Opa?"

On a hot day it is important to get into the gardening before the sun gets too high. So Martin and then Zach helped Opa tending the garden, gathering ripe vegetables and trimming and digging as required.
As the sun rose, Zach worked out a very natural way to stay cool.  He discovered the perfect leaf with which to provide just the right amount of shade. He then proceeded to wear it outside and inside until it perished through wear and tear.
