Modern Guiness is corporate propaganda.

I hear bats, absolutely. I can hear electronics as well, and some are just so frustrating. I've never heard a dog whistle, as in I've literally never seen one in person, but there's a house near to me that has a warning thing when someone approaches their yard, probably to ward off dogs? But my god, it's loud and high. I try to avoid that route at all costs.

Off topic, but I’ve not seen that emoticon before (unusually left-facing too!) and it’s adorable.
