Three quotes based on the thematic theme of "Traditions & Customs vs Change" in Things Fall Apart in Chapters 8 - 11 only

Chapter Eight

"All their customs are upside-down. They do not decide bride-price as we do, with sticks. They haggle and bargain as if they were buying a goat or a cow in the market."
"That is very bad," said Obierika's eldest brother. "But what is good in one place is bad in another place. In Umunso they do not bargain at all, not even with broomsticks. The suitor just goes on bringing bags of cowries until his in-laws tell him to stop. It is a bad custom because it always leads to a quarrel.

This is the only quote I find that fits the topic of change. I will read through the text again to see if I can find anymore.
