Deltiology

Alright, kiddo, have you ever received a postcard when someone is on vacation or when they want to say hello from far away? Well, deltiology is the study of those postcards and collecting them as a hobby.

Imagine you have a big box and every time someone sends you a postcard you put it in the box. Now, imagine you start collecting postcards from all over the world, from different cities, countries, and even old postcards from long ago. That's really cool, right?

That's what deltiology is all about, collecting postcards from all over the world and learning about different places and times through them. People who study deltiology love to organize their postcards in special ways, like by theme or by country or even by the stamp on the back.

So, next time you get a postcard from someone, think about it and maybe start your own little deltiology collection!
