Some days I am there, and he comes over to me, apologizes for interrupting me in my work, and asks me if I can recommend a book for him to read. He does not know me, and I do not know him. I ask him if he is interested in literature or science, and he tells me he is interested in anything that is worthwhile. I suggest a book, and two hours later he returns, thanks me, and tells me he has finished reading it, is there anything else I can recommend.
