Oh, I get that all the time...

Ok, not all the time. But I have been emailed on multiple occasions to be told that I have chosen the wrong word for my book blog title. Since it's about books, not bugs, I clearly meant "etymology," not "entomology." Because one is the study of words, and the other the study of bugs. And here I thought I was being clever. Ah, well.
