This is my uncle. His name is Ryan. He’s strong and big. He has short, curly hair. He works on his farm. He raises many cows, pigs, and chickens. His farm is near his house. Just go along Blue road, and it’s on the right, next to a lake. He goes to the farm on foot. Yesterday was Sunday. He wasn’t on the farm. He was at the museum with his family. They love watching old things. It was exciting.
