Today, I wrote 2 emails in Korean. One of those was a reply to a penfriend, who contacted me once already, back in 2015, not long after I started to learn Korean. She noted that she's amazed at the progress I've made since then. It's very funny, because now, that I've updated my profile with a Korean introduction, and I placed that in front of the English one, I seem to be very popular on the language exchange website.
I also learnt some new grammar from My Korean Notebook.
