Dear [Your Friend’s Name],

I hope this letter finds you in in good health. It’s been so long since we last caught up, and I thought I should take a moment to write you a letter.

I just had the chance to visit the mountains with my cousins. The landscape was wonderful, and we had the most astonishing time hiking and discovering nature tracks. Recall how we got lost on that track for a while? It was quite a venture!

I heard from Harry that you’ve started your own business of photography and that is really a fantastic news! Your talent behind the lens has always astonished me, and I’m not at all astonished that you’re standing for yourself. Let’s not wait so long before our next chat. How about we plan a coffee date next weekend? I’d love to hear more about your photography business and share more about my new job. Drop me a text or an email, and we can work out the details.

Take care and looking forward to meet you super soon!

Best Regards,
