The human psyche has a duality that is the basis for our entire personality. It’s a mixture of feelings, thoughts, and desires that both good and bad. The two sides of the personality are known as the id and the ego. There is often a battle between these two factions as to which side should be dominant. One girl may have a nicer side as well as a dirtier one, but the nice side usually wins out in some way,but not this time see her legs closed vs her legs wide open when she see the mighty dollar.
