The Feudal System - Extension task!

Father Francois, you are my honored guest. Please allow me to explain the Feudal system to you before you ask any questions of me. I am but a simple farmer. The Feudal system is a system of give and take. The lord would give off his land to a vassal for his support in return. If the vassals keep his oath, he could keep the land, if not, it would be returned back to the Lord. Vassals could follow the same system and become the Lord to his Vassals. The king still owned all the land.
