Can you help me find an old question?

I’m really racking my brain to remember who asked this old question I keep remembering. Search (both the “in house” search and Google proper) have been no help to me. So maybe someone else remembers this.

Within the last year or so, a lady jelly received a mysterious book delivered to her home. It was called On Being Certain by Robert Burton. She didn’t order it, she didn’t know who might have sent it, it just arrived one day with no clue whatsoever as to its provenance.

Did she ever find out who sent the book?
Did she read it, and if so, did she like it?

Based on that Fluther question, I ended up ordering a copy for myself, and am enjoying it immensely. And I’m wildly curious as to how this turned out…
