Dear John/Sally,

I hope this card finds you well. I wanted to share with you the wonderful memories I made during my summer holidays. From sunny beach days to exploring new cities, my summer was filled with excitement and relaxation.

I hope your summer was just as amazing and that you were able to create special memories of your own. I look forward to hearing all about your adventures when we catch up.

Wishing you the best and looking forward to seeing you soon.

Warm regards,

[Your Name]
