Hello, (friend's name)! In my last letter, I wrote to you about how I spent my summer. Summer is over, school days have begun. My first day at school was spent at home, since no one goes to school now, everyone studies remotely. All lessons were held in the app for learning. We were given tasks and we did them. There weren't many lessons, because we were just starting to learn. In all the lessons, we repeated the topics from last year. That's how my first day of school went. I'm sorry, but I have to stop writing because school has started and I have to get ready for class. It was your pen friend. Bye!
