MR DIAHO-MONAHENG
Sir, to answer your question, a person who gave instructions, would never give instructions without any certainty.  He gave you instructions with the certainty that that is the situation, and you have to carry out what he tells you.
	If ever you do not understand how the work should be carried out, you then ask for clarifications because the person sends you to a place, knowing exactly that there will be no changes and no additions at all, I don't know whether I answered your question sir.
