The rusty,weather worn ship did not seem sea worthy
If you found information in a book as well as a website then use both. dont erase the page number cause you never know what youll need it for. sence your using a website youshould give cretit to the places you got your information from and the pae number will count as a resource so i would prefer you to keep it.
you kinda worded it weird so if my answer doesnt help then im sorry.
It would be too obvious for me to write the entire letter for you, but I'll include a list of points that you could include in your own writing style:
* Thanking Lee for his letter, and saying that you are happy that he is having a good time.
* Telling him roughly what you're studying at school (without being boring).
* Write about what you would like to do when you leave school.
* Finally, say that you miss him a lot and look forward to hearing from him soon.
