The Hollow Tree or How to catch a man!

When we were walking up this lane this morning we saw a head rolling around on the base of a sawn down tree! Gradually a little more of the torso appeared. A young lady had slipped down into the hollow core of the tree and completely hidden herself, emerging to everyone's surprise, bit by bit.
She couldn't get out on her own and had to be pulled up by two sturdy young men. If you need to find a man ....... well, there are probably easier and safer ways to do so!!!
