Great example of “come away with!” I would make a few small edits: “I like the concept of happy endings, which are widely used in Hollywood. It lets viewers come away with a feeling of elation.” I think you can just end it there and we’d know what you’re talking about.

That’s great. You can clarify what you mean by saying, “Last month, I stayed on the beach for 24 days, working remotely. I came away from the experience feeling better.” Interestingly in English, “home office” means a room in your house where you work. But what you call “home office,” we call “working remotely.”

Perfect example – just make “come away with” in the past tense, so it reads: “After reading a report on the war in Ukraine, I came away with a bad feeling about the world economy.”
