There are many themes in Fugard's play. Consider the theme of how apartheid affects interracial relationships. Hally because of
his race, spits on Sam without any consequence, and thus breaks the boundaries of their friendship. Based on Hally's character traits and Sam's peace offering, what choice do you think Hally will make? Will Hally fall into his privileged position and close the door to Sam's peace offering, or will he change and renounce discrimination?
Apartheid, no doubt, has determined life in South Africa during the period 1948-1994. Families had to work hard to overcome this situation. It needed strong determination of people affected by this fact who were permanently being challenged about their own feelings and family principles. In this case I consider Hally will accept Sam's peace offering since the feeling was strong enough to deal with the details of this situation.
