Light-hearted.
Examples. As a teen I worked in a shop, sometimes something doesn't scan and the customer (if paying attention) without fail would say, "Oh, that's free then?" Followed by a chuckle.
I wear very high heels a lot, I get told all the time, "How you don't break your neck in those, I'll never know!"
The latest one, my DP is a head chef, people always say, "Oooh, I bet you get loads of lovely meals cooked for you!" I bloody wish, it's a Busman's Holiday for him, he doesn't want to cook after a day in the kitchen. 😆
