What is so ironical about Resian's plans to go to Egerton?

"I don't want to be a parent. At least not in the foreseeable future. I want to study. When I‘ll have obtained my degree, other peripheral matters, such as a husband, children, and such may be considered”

Throughout the novel, Resian believes that she will one day leave Nasila to attend Egerton. When she finally confronts Ole Kaelo, she believes Taiyo has already told her father about her aspirations. Unbeknownst to Resian, who thinks she's heading to university, the reader knows that her parents are preparing for her marriage to Oloisudori.
