Dear, (insert principle's name here)
I would feel so honored if I could have to opportunity to go to Ilam for four whole days. I honestly do feel like it would be a great stepping stone in my education. I'll be completely responsible, respectful, and safe if I do get to go. This would be a amazing experience for me so I can get a basic knowledge on the outside world and get to know some of the historical buildings, or landmarks around the city! I would be extremely grateful for this opportunity if you allow me to go. Thank you for taking your time out if your day to read this. Have a great rest of you day.
Sincerely, (Insert your name here.)
