Clarence:A Hard head makes for a soft behind

Dormer being added to ancestral ranch. Framework in place & flooring down. Last request to this "old peep" by construction crew: Please, Mr. Washington allow the flooring to set 12 hrs before you go up. So an hour later while my mother is prepping dinner who "decides" to take a look? According to my Mother; she heard a snap and my father saying "oh shit" before one of his legs came thru the ceiling. Her assist to this "old peep" was only the comment: they told you not to go up there, and returned back to her cooking while the other "old peep" figured out how to extract his leg.
