I read Me Talk Pretty One Day because I thought it was about grammar. Despite my misconceptions (it's short memoirish stories), I thoroughly enjoyed it, and picked up the latest by the same author, Dress Your Family in Cordroy and Denim.
It's my kind of humor: the wry irony with a dash of obscure hyperbole. But besides that, there's a good deal of personal quality to the stories that makes me feel like I'm actually there with David Sedaris and his family. That's what makes each story good. [shrug]
