For my part, I am going to read a variety of poetry that week. I know little about poetry and am not sure yet which form best pushes my buttons, so I have been planning to branch out for awhile to find something that I'll enjoy. As of now, my favorite poem still remains Annabelle Lee by Edgar Allen Poe. During a former Edgar Allan Poe celebration week, I posted a video post.
