Dear Dad,

I hope this letter finds you well. I just wanted to let you know that I am going to spend my summer vacation in the USA, specifically in New York. Aunt Lucy lives there, and I plan to stay with her for three weeks.

I am very excited about this trip and looking forward to exploring New York City and experiencing everything it has to offer. I will make sure to stay in touch and keep you updated on my adventures.

Please don't worry about me, I will take good care of myself and Aunt Lucy will be there to look after me. I promise to make the most of this opportunity and create unforgettable memories.

Thank you for allowing me to go on this trip, I truly appreciate it. I miss you and can't wait to share all my stories with you when I get back.

Take care and see you soon!

Love,

[Your Name]
