Dear Dasha,

I hope this letter finds you well. It's been awhile since we last spoke, and I wanted to take the time to reach out and see how you've been doing.

I've been thinking about the fun times we used to have together and how much I miss our friendship. Life has been busy lately, but I would love to catch up and hear all about what's been going on in your life.

Please know that you are always in my thoughts and I cherish the memories we shared. I hope we can make plans to see each other soon.

Take care, my friend, and I look forward to hearing from you soon.

Warm regards,

[Your Name]
