My mom's friend Wendy is teaching nursing in Rwanda for a year. Rwanda is a country in Africa where they had a genocide (but not the one we read about in A Long Walk to Water) so they lost a lot of the people who were doctors and nurses. Wendy is there to teach people to be nurses at a hospital in the capital city. Since she is in Africa, she gets to do a lot of things the rest of us can't do.
For example, she sent me and Jack a postcard from Burundi, which is a neighboring country. She said Burundi is going to have elections next year and there might be trouble, so she had to go now. According to wikipedia, Burundi is one of the 5 poorest countries in the world.
The other cool thing Wendy got to do was go to Volcanoes National Park in Rwanda and hang out with gorillas!. My mom showed me a picture where Wendy is in the picture, and there's a bunch of gorillas just lounging about behind her!
