Forgot!

I'm so sorry, I forgot. There was a post it note with the letter.
I tried to take a photo of it, but it was too blurry to read:















I'll type up what it says:

- Horatio is to himself
- Ill Hamlet lost 4 letters
- The opposite in the first clown's reply.
(There is an arrow from ill to opposite)
- At the heart of the Laertes line.
- Hamlet is to Horatio
(Says Horatio upon his entrance)
- Gone for Hamlet, longest returned for you.
