Lucas- Camping? But, next week, the weather will be awful, you know?[Can 「でしょう」 be used both in a rhetoric tone as well as in an affirmative one? As for meaning, it's like "probably", right?] [「キャンプ」 is the right word because it's a suru verb and noun while 「キャンピング」 is only a noun, right?] Josh- Really? Well, then I’m going to work on my [NON-PROFESSIONAL] tennis skills [safely] inside the club. [Does ｢練習｣ have seriousness implied? If so, what should I have said?] Lucas- Not humble at all, don't you think?/Oh, so that's how it is. [Well, Josh did just snob the heck out of Lucas' friendly invite, so I thought it'd be okay to say something like that. Jokingly, of course.] [Would ｢全然卑しくないね？｣ be correct? I admit that saying "Your head isn't low at all, is it?" is a bit weird.] Josh- Do you want to be my [TRAINING] partner? [ Again, not for SERIOUS serious play, just for lols, chitchat, idk. I did mean to say partner, though, just not anything related to love or sex. Did I accidentally create an erotic situation in my story? Haha, I won't be forgetting that one if so.] Lucas- I take that back. But, are you for real? Josh- Yeah, taking just one non-member with me to the tennis club is free, so it’s fine. [Is it actually clear enough or were you just too lost to say something for certain?] Lucas- Yay, you’re the best! 色々ありがとうございます！長いカキコにはごめんなさい。こっちはジャガイモの顔文字です。 (「Thanks a lot for your patience, your attention and everything! And sorry for the long post/ramble, here's a kaomoji potato.」と言いたかった。) (╮╯╭) If that doesn't look like a potato for you, just look harder until it does. [Apparently my neatly organized paragraphs turned into a giant wall of text. And asterisks don't produce boldface. How fitting.] [2/2]

[You may skip to the English explanation of the dialogue if you want. I have a bad tendency to ramble for too long, which started all the way back when I was...] *TO START-* First, thanks for the feedback, Toshi-san and Miki-san [I apologize if I mixed up your first name with your last.].Second, sorry for taking so long to reply. Third, trying to explain something in Japanese is way beyond my current level, so I'll stick with English for everything else in this entry (and I'll be sure to include an English version of the dialogue right from the start in the future). *STUDENT’S NOTE-* I feel like I should mention I tried to restrict myself to only use words/expressions that I'm either familiar with [not through text production, just through grammar guides,online dictionaries,example sentences,etc.] or that I feel like I might be able to use correctly. While the result was, indeed, a mess, I feel it was a valuable learning experience. *COMMENTS ABOUT THE STORY-* I'm also not too sure about it, which is always a good thing to hear. I didn't think *much* about it, but trying to write something more complex would've been a recipe for disaster, probably. I meant for Lucas and Josh to be close-ish friends, with Josh being the rich [stingy,maybe?], stuck-up friend who, despite acting arrogantly, really likes and respects Lucas [maybe?], and Lucas being the snob's friend that's used to his snobbishness. Also, this is based entirely on my prejudice, but I've always thought that going to a club to play tennis recreatively is a rich person thing. Never looked at any prices, though. Again, not much thought. *STORY EXPLANATION-* [I at least got the greetings right, right?] Lucas- What are your plans for the weekend? I’m planning on going to the karaoke bar, would you like to go with me? Josh- Uh, I intended on going camping, so it’s not gonna happen. [「あっ」 was supposed to be a filler word that emphasizes Josh's indifference...I think.] [1/2]
