I had a change of perspective - literally - after discovering foxglove plants that were six to seven feet tall. I felt so little - which is how my (potential) readers must feel all the time. It was different than hiking among, say, redwood trees. I expect them to be huge. Flowers? Quite a surprise.
Note to self: to tell stories for children, remember to sit down. View the world from three feet above the earth. The scale is so different.
