I'm going to take away my friends sleeping arrangements
Don't you think it's rude to take away their sleeping arrangements? Why would you do that?
Because then he'll appreciate what he had before.
I do not think that this is your place to do that. You should not intentionally make your friend uncomfortable.
Life is hard I'm sure he can handle it.
Even if they can handle it, it is still wrong of you to purposefully make them uncomfortable and make them feel distressed in the process. I do hope you change your mind and unless this affects you, you should mind your own business as he should and keep his sleeping arangements.
