Dear friend,
Thank you so much for your letter. It was very interesting to learn about your granny and your Christmas present.
As for me, normally I celebrate all holidays with my family, since we are very close and love spending special times together.
My favourite holiday is, of course, my birthday. I love it because it is the day when I receive all the attention and love from my family and friends. Usually we celebrate my birthday at home, and my mom bakes a special birthday cake for me.
The best present I've ever received was the coolest bike my dad gave me for my last birthday. I have been riding it ever since and enjoying it so much.
Looking forward to hearing from you soon again!
Sincerely yours,
yourname
