Dear Mom,

I hope this letter finds you well. I wanted to share with you my summer plans, as I will not be coming home for the holiday this year. This decision was made after careful consideration and discussions with my academic advisor.

The opportunity has arisen for me to participate in a research project that aligns with my academic interests and career goals. This project will run throughout the summer and will require me to stay on campus. It's a chance for me to gain valuable hands-on experience and make significant progress towards my studies.

While I will miss being at home with you all, I am excited about this adventure. I plan to keep you updated regularly through calls and video chats. Please don't worry; I will take good care of myself and stay safe.

Thank you for your understanding and support. I promise to come home as soon as I can for a proper visit.

Love always,
[Your Name]
