I’m working on a english writing question and need a sample draft to help me learn.

Question: Mengestu writes, “It’s easy to see now how even as a family we were isolated from one another—my parents tied and lost to their past; my sister and I irrevocably assimilated.”
What does he mean that he and his sister are “irrevocably assimilated?”  What are two examples that show how they’ve assimilated (or became assimilated)? How do you think their assimilation affects their relationship with their parents?
Guidelines: You are proving an understanding of the overall reading as you answer the question. Make sure to use examples and specifics from the text. 

You should also make sure that you understand the meaning of assimilation in context of the story.  Look at several definitions and find the correct meaning. You can also see me and we can discuss!
There are two examples of how Mengestu has assimilated. He doesn’t mention his sister when he gives the examples. He assumes the reader understands that she assimilated in the same manner.
