As heard from my dear sister, Shaina, last night :
[backstory : we were bored and were making origami creations from our napkins]
Shaina : that looks like an old diaper
Mia : you mean like a cloth diaper?
Shaina : yeah. Why did they have those, anyway?
Mia : cloth diapers?
Shaina : yeah
Mia : plastic diapers weren't invented yet
Shaina : really? How weird. But still...why did they use them?
Mia : because they were sick of shoveling baby poo off the floor
