Answer:
Dear Grandma,
I hope this letter finds you well. As you know, my birthday is coming up in just a few weeks and I wanted to make sure that you knew how much it would mean to me if you could come celebrate with me.
This year is particularly special because I'm turning [insert age] years old, and I would love nothing more than to spend my special day surrounded by family and friends, especially my dearest grandma.
I've planned a small party at my home on [insert date and time], and I would be absolutely delighted if you could make it. I'll have all your favorite foods and treats, and we can spend the day catching up and reminiscing about old times.
I know it's a bit of a journey to get here, but I would be more than happy to help you with transportation and any other arrangements you might need. Please let me know if you'll be able to make it, and if there's anything I can do to make the trip easier for you.
Thank you for always being such an important part of my life. I can't wait to see you again and celebrate together.
With love,
[Your name]
