Read the given passage and answer the questions that follow.

Ahoy there, matey! Today, we’re going to talk about something near and dear to my heart: pirates. You know, those swashbuckling scallywags who pillage and plunder on the high seas. Now, when you think of pirates, you might picture them as these tough, intimidating figures. But let me tell you, there’s a lot more to these buccaneers than meets the eye. For one thing, have you ever noticed that pirates seem to have an unusual fondness for parrots? I mean, come on. They’re birds. What use could a pirate possibly have for a bird? And then there’s the whole eyepatch thing. Yes, pirates are known for wearing eyepatches, but did you ever stop to wonder why? Some people think it’s because they lost an eye in battle, but the real reason is much simpler: it’s so they can switch the patch from eye to eye and maintain night vision in both eyes. Genius, right? But my favourite pirate quirk has got to be their love of treasure. I mean, who doesn’t love a good treasure hunt? But the way pirates go about it is just hilarious. They’ll spend months, even years, searching for that one elusive chest of gold, only to bury it on some deserted island and forget where they put it. It’s like they’re playing an eternal game of hide-and-seek with themselves. And let’s not forget about their vocabulary. Pirates have a whole language all their own, full of terms like ‘shiver me timbers’, ‘avast’, and ‘yo-ho-ho’. I mean, what does any of that even mean? It’s like they’re speaking a different language entirely. So, there you have it, folks. Pirates might be fierce, but they’re also pretty darn funny. Who knows? Maybe we could all learn a thing or two from these salty dogs.

What is one of the pirate quirks mentioned in the passage?
