Hi, I'm reading this book and this sounds like a non-sequitur: "My, you students have a cushy life, don't you?"

I'm not sure what it means and I'd like some clarification. It sounds like a non-sequitur because the narrator and another character have been talking dealing with the death of a loved one.
It means that things are very comfortable for them. Perhaps the speaker thinks the students are sheltered from the cares of the outside world, meaning both physical comfort and emotional?
Perhaps you can provide more of the context. Barb's interpretation seems reasonable on what you have given.
Students: Are you brave enough to let our tutors analyse your pronunciation?
That would seem absurd because the 1 of the 2 characters involved with that phrase has been told the death of a loved one. Not a single bit comfortable.

By the way, this is from Kitchen by Banana Yoshimoto.
I was only trying to help. I assure you, I won't trouble you with any of my absurd suggestions in the future.

I can't see any other meanings other than the one Barb gave....but of course it would be quite possible for this to be said in a teasing/critical/sarcastic manner. In fact, I would think it is more likely to be said in that sense and in this context could be a comment on the other person's reaction to the news of the death. Did they over-react in some way? Then perhaps the speaker was being sarcastic in the sense of 'you've clearly never had to face anything like this before. What an easy life you've had.'

Don't be rude to Barb - she helps a lot of people brilliantly. Emotion: smile
