Its saying like they don't want nothin to change and that no matter how hard they tryna change it its gone stay the same no matter how wrong/ bad it is.
Good manners convey respect to those you interact with, and also commands respect from those you interact with. Right conduct is living in a moral and ethical way in the absolute sense rather than by the standards of any particular time or society nation

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.
