Michael was always exploring wondering how this and that came about, at a very young age.
While walking along a river bank, he came upon a hole which seemed to go quite away into the bank.
Deciding to venture in, and hoping the bank didn’t cave in on him, he took a few steps in very quietly.
All of a sudden a light appeared on the side of the wall.
Shocked set in, he thought someone was coming out.
Needless to say, he got away out of that tunnel very quickly.
Years later he ventured back to that hole when dusk was setting.
He found out what that light was, Glowworms.
