Answer:
Hi there!
my best attempt to answer this question would be to suggest dome prompts which you could possibly include in your writing...sounds good?
So you have the option of first introducing your cousin (her name,country she travelled to, comparisons example was the food great,why she travelled to the country you chose perhaps a job or maybe to meet someone)
Then you could go into detail about the experience (here speak more about the cultural shock or weird customs for instance)
summarize it by simply stating was the experience good or bad? What she wished she could've done before travelling, regrets or even tpositive aspects
It'sall upto you and your imagination
Goodluck with writing!
