He was out in the garden again, collecting leaves.
Well, not exactly collecting, but measuring. There again, measuring isn’t the right word either, grading is more like it. Grading the various green colours of leaves. He was certainly spoiled for choice, there were so many of them. They varied from the very pale green through to the very dark. He had gathered his latest pile and was sitting cross-legged with them in front of him. He studied the collection with interest before sorting the dozen or so samples into a row in front of him. He looked at each leaf very carefully before placing it down in its proper place. He then took the sticky tape out of his pocket and, pulling out a long length of it, placed it carefully over the row of samples. Holding one end, he stood up. With his latest leaves dangling beside him, he went back into the house.
