Dear [Penfriend's Name],
I hope this email finds you well. I wanted to share with you what I usually do with my friends in my free time. We have a lot of fun together!
One of our favorite activities is going to the movies. We love watching the latest films and discussing them afterwards. Sometimes, we also organize game nights at someone's house. We play board games, card games, and video games. It's always a great way to bond and have a good laugh.
Another thing we enjoy doing is going on outdoor adventures. We often go hiking or biking in nearby parks. It's refreshing to be surrounded by nature and it helps us stay active and healthy.
Lastly, we love trying out new restaurants and cafes. We are food enthusiasts and enjoy exploring different cuisines. It's always exciting to discover hidden gems in our city.
That's a glimpse into my free time activities with my friends. I would love to hear about yours too!
Take care and stay safe.
Best regards,
[Your Name]
