Kairos and Bones

In the midst of the hustle and bustle of the flea market, Kairos and his friends entertain themselves by walking around and exploring the stalls full of curiosities and extravagant objects. Bones stops in front of a vendor offering an assortment of wristwatches with extravagant designs and strange functions. Seller: Hello, hello! Would you like a watch that stops time? Kairos (laughing): Stop time? That sounds useful! But wouldn't that be a little... dangerous? Salesman (smiling): Nothing to worry about! You only use it at convenient times, like when you realize you forgot to buy your friend's birthday gift.
