For Example

For example, if a person buys a chocolate bar and offers some to his friend, that seems like a noble act. However, what if a random person were then to say: "Hey, may I please have some?," the owner of the chocolate bar may be like: "Who are you?" Even though he may then honor the request, not wishing to insult the person, the giver may not really want to give him. This example shows that the person who offers to share his chocolate bar, does so because he feels a level of comfort and connection with the person he is offering, and offers out of a natural desire to want to share with that person. Therefore, although it seems like a noble act on the outside, I am not sure of the extent to which we could consider that person a tzaddik. It does not show a courageous act of fighting his instincts.
