Try convincing your parents to let you live alone in an apartment.
Listen, actually, I'd like to live on my own in an apartment.
I've already got a job and I think I can pay the rent.
Besides, I think I should look after myself for the future.
I need to learn to take responsibility for cooking, cleaning, laundry, garbage and so on.
What do you think about that?
I would like to enjoy the scenery of unfamiliar towns from my train window.
Because I don't think it's a bad idea to be in a daze while looking out once in a while.
And if I get tired of doing so, I think I will read a book.
