Answer:
Hello friend, it is (your name) and I hope this letter finds you in peace and prosperity. I would like to discuss some cultural aspects of my day to day life for you to get a clear understanding of my culture. Some traditions/holidays that have occurred or are coming up include Halloween, Thanksgiving and Christmas. Not everyone chooses to celebrate these holidays but they are popularized in the U.S. The one that I personally resonate with is Christmas. This holiday surrounds gift giving, food, and having a positive spirit. For my family's and others, leading up to this holiday we watch movies, festive crafts and even pick out a Christmas to be the center piece of our house. Around this time, when getting into the spirit, some many choose to decorate their house with a Christmas theme in mind. Overall holidays are a fun way to feel connected and grateful for your loved ones. I hope I will soon hear about your special cultural aspects and traditions.
Sincerely, (your name)
