Limestone is a common type of sedimentary rock which I find uncommonly interesting! It’s mostly calcium carbonate, which is also what eggshells 🥚, seashells 🐚, and pearls 🦪 are made out of.

In places where it rains a lot, limestone erodes easily, which results in simply gorgeous landscapes such as:

Hạ Long Bay in Vietnam

Tsingy de Bemaraha National Park in Madagascar

The Li River in China

Additionally, the world’s longest (Mammoth) and deepest (Veryovkina Krubera is once again the world’s deepest cave, thank you to SockOlm for pointing that out) cave systems are both found in limestone formations

Mammoth Cave in the United States

Veryovkina Cave in Georgia/Abkhazia/Russia (disputed territory)

    Okay now I wanna know what the subtle hints are cause this sounds like a sitcom 😂

    I promise you, coming out even just to your friend will feel like a huge weight off your chest.

    I know extremely well the imposter syndrome you’re clearly feeling. its something many if not most of us have felt. And it sounds like you want confirmation or validation of your transness from your friend, which is something I very much doubt a confused cis person would do.
