I think postcrossing is fun! This way you can experience the feeling that you're an "inhabitant of the global village".
I'm a female in my sixties, retired since April 2020, and I live in a quiet small town with a beautiful old towncentre in the middle of the Netherlands.
I like postcards with:
hares or foxes;
paintings/drawings (art-cards) especially made by artists from your own region or country;
children's book illustrations;
tractors, harvest machines, farming and countrylife in general;
Russian and East-European folk art;
daffodils, anemones and poppies;
snow and snow landscapes;
If you're from Russia: I love to receive Russian landscape paintings.
In december I love to receive Christmas cards and stamps!
By the way: my favourites list is my wishlist!
Oh, and I do love nice stamps!
Love and happiness to you all!
