Wooden Planking

I was astounded seeing Son's stretched body across the chair, face down and arms by his side, trying to stay immobile. He stole a sideways look at me, then relaxed himself and cautiously let himself down.  He grinned and said, 'I'm planking'. Huh?

Son proceeded to explain this craze, then coaxed me into trying it. I hesitated, then my curiosity got the better of me. I chose the floor instead of the precarious looking chair, followed Son's guidance and found my face in close proximity to the concrete floor.

'Great mom', I heard Son suppressing a snigger, 'you are real wooden..............'
