Let’s bright up someone’s day by sending them a postcard!
There’s a wonderful charity project https://vk.com/dobropochta
that’s been running for 5 years in Russia. The idea is to send a real, that is, paper postcard by mail to someone, mostly children, who’s going through a tough time battling with a serious disease, cheer them up a little and just make them smile. No money donation is needed.
Now as there’s no certain probability that either a child or their family understand English, this could be a fantastic opportunity for those learning Russian to write in Russian! If you want, you could also Google translate your message into Russian, and include the translation.
