Peter is going to leave in half an hour. He is going to finish all of his work before he leaves. I’m going to eat lunch at 12:30. After I will take probably a nap. I’ll get home around six. When I get home, I will call Sharon. I’m going to watch a TV program at nine. Before I watch that program, I’m going to write a letter to my parents. Gary will come soon. I wait here until he comes. I’m sure it will stop raining soon. As soon as the rain stops , I will walk to the drugstore to get some film. Right now I’m a junior in college. After I graduate with a B.A. I’m going to enter graduate school and work for an M.A. Perhaps I will go on for a Ph.D. after I get my Master’s degree.
