Hey [Friend's Name],

I hope this email finds you well. I wanted to share with you how my Tet holiday went. It was absolutely amazing! I spent quality time with my family, indulging in delicious traditional food and exchanging gifts. We also visited our relatives and paid our respects to our ancestors. The atmosphere was filled with joy and laughter. We played traditional games and watched stunning fireworks displays. It was a much-needed break from work and a great opportunity to relax and recharge. I feel so grateful to have experienced such a wonderful Tet holiday. How was yours? I can't wait to catch up and hear all about it.

Take care and talk soon!

Warm regards,
[Your Name]
