Summary
Analysis
In Pennsylvania, Caitlin and Caitlin’s mom both reach dead ends in trying to find Zimbabwean sponsors for Martin’s education. Damon starts getting annoyed with Caitlin about all the time she spends studying. When he says he’s sick of hearing about Martin, Caitlin gets angry with him.
It’s unsurprising that Caitlin and her mom have a hard time finding Zimbabwean sponsors, given how poor much of the country is and how powerful the U.S. dollar is in the exchange rate. The fact that they even started looking abroad suggests that they have already thoroughly investigated their domestic options with no luck.
