I had a coworker approach me on break and start telling me about a book he was reading and how much he was enjoying it. Towards the end, he mentioned struggling with it and that he wished someone had told him how great reading was earlier. We were both damn near 30, and it was a YA novel. I resisted the asshole urge to roast him because, shit, at least he’s trying?

Struggling how though?

If they were struggling with the vocabulary, then that might be roastable.

But if they meant, e.g., struggling with the themes, that might be understandable. YA books sometimes tackle difficult subjects or are subtle, layered, etc.
