First off, let me say I read Lawson's second book (Furiously Happy: A Funny Book About Horrible Things) first because life sometimes happens that way. So the prequel experience was strong for me here - references made in Furiously Happy are explained here, and those to the second book are happily recalled. 
 The through line of the stories here are about embracing and celebrating the absurdities life serves up to each and every one of us. Not that they are the same ones, as life is a far craftier and imaginative server than we'd care to admit. Still, there are stories of Ms. Lawson's mental and physical challenges, her love of taxidermied animals, and dialogue that (to me) shows that her brain must be running ALL. THE. TIME (like Robin Williams). 
 Much like another favorite memoirist, David Sedaris, once you've read one of his books, you have a good idea of the look and feel of the others. If you liked what you've just read, you're in luck, and if not, you're better off spending your reading budget elsewhere.
