Hi Robert,
How are you? Did you GOT a back to Kenya without any problems. I hoap so. Since we left New York, I have be thinking a lot about the project and what we talked about in New York. Why dont we write about the differences between education in Kenya and education in brazil? we can do thinks like compare the coarses that students can study in university. We can inviting readers to send questions about Kenyan and Brazilian schools to website blog and we can write apropriate answers. we can also describe a typical school in our countries. What you think? Does it sound like a good idea?
