I once as a young electrical apprentice installed some wall lights for my sisters friend after chasing the wall and installing the cables I then plastered the cables in the wall with the plaster I had which was from the cellar in my home, a couple of days later my sisters friend said that the plaster was still soft, it wasnt until a few months later that my father went to the cellar to search for a bag of white wash to paint the yard that I realized that I had plastered the wall with white wash and not the bag of plaster hope this brings a smile to some
