What loves to talk but has little to say,
Nags you in the morning and throughout the day?
I get that this one comes across as too short or too broad. There's not much I can do about it now, but please understand I was trying for something inspired not only by Avigrail's wife but also short, simple riddles that play with the double meanings of words, like "Black and white and red all over".
I can imagine I would've got absolutely murdered if I went with my other idea instead: "What's fast unless it runs. And ruins the laundry."
