The word 'hostile' means

Directions: Read the following passage carefully and answer the question that follows:

It is a big point in ethics whether it is dishonest to rob one’s own money-box. Obviously, each of us consists of two selves, the self that wishes to save and the self that wishes to spend and one of them differs as much from the other as a man does from his first cousin. Not only this, but each of them is hostile to and distrusts the other. The self that saves feels himself thwarted at every turn by the self that spends, and the self that spends is irritated by the knowledge that the self that saves is constantly watching him grudging with every penny in his fingers. When the self that spends sees the self that saves stealthily slipping a penny into the money-box, he longs to cry: ‘Stop thief! That belongs to me’ and when the self that saves sees the self that spends forcing pennies out of the money-box with a chisel, he too feels like crying out in anguish, ‘Stop thief! Everything in that box belongs to me’. There is, indeed a tragic position. Each of them serving a life-sentence in the other’s hated company and unable to escape from his neighbour as one of the Siamese twins.
