telling two people you are halfway through a book (which I was) that you expect will take at least 3 days to finish before you can start beta-reading their books.
And then not only finishing that book (The Man In The High Castle by Phillip K. Dick which was terrible and had an awful ending) but also then reading both of their books (that’s over 80k words), proofing them and returning comments.
And still having time to watch a classic first season B&W Twilight Zone episode.
(Which was “To Serve Mankind”, very enjoyable)
