小明：Hi John, how's everything going？
John： It's okay, just a little stressed out about upcoming exams. How about you? 
小明： I'm doing fine, but I have to admit I'm quite worried about my English writing class. I'm still not confident enough in my language skills.
John： Don't worry about it too much, you're doing great. Just keep practicing and find someone to proofread your writing before you submit it.
小明： That's a good idea. Do you know anyone who could help?
John: Sure, I'd be happy to read your work and offer some suggestions.
小明: Thank you so much, John. That's very kind of you.请总结以上对话的主要内容。
