In her book "Furiously Happy: A Funny Book About Horrible Things," author Jenny Lawson humorously reflects on the idea of having pockets as magical as those found in the TARDIS or Mary Poppins's carpetbag. She expresses a whimsical desire for pockets that can hold much more than they appear to, evoking a sense of wonder about the practicality of such magic. This notion speaks to the everyday challenges of carrying items that often feel too bulky or numerous for regular pockets.

Additionally, Lawson questions the necessity of Mary Poppins's impossibly large bag, which seemingly can contain anything. She humorously speculates on why Mary Poppins, who has access to magic, would need such a big bag in the first place. This playful critique hints at a deeper frustration with the limitations of ordinary items and societal expectations, ultimately drawing attention to the absurdity of these whimsical designs in fantasy compared to real life.
