Jorge is shopping at a clothing store. Salesperson (Lily): This jacket fits you really well! Would you like to size up and try a bigger size? Customer (Jorge, confused): Size up? You mean bigger size? Lily (nodding): Yes, exactly! "Size up" just means trying a larger size than the one you have. Jorge (scratching his head): Hmm… Size up? You mean, when I grow bigger? Lily (laughing): Haha, no, no! "Size up" just means trying a bigger jacket. Not growing, just a bigger size! Jorge (still confused): So… Size up means I wear bigger clothes, but I don’t grow taller? Lily (smiling): Yes! "Size up" means getting a bigger size of the same jacket. You don’t need to grow taller for that! Jorge (nodding, still unsure): Okay, okay, I try bigger size jacket. I think I understand! Jorge (curious): By the way, your English is really good. How do you speak so well? Lily: Well, I took speaking lessons with Teacher Smith on italki! She’s amazing for improving English. Jorge: Really? How I book lesson with her? Lily: It’s super easy, just click on her profile on italki and book a speaking lesson! Jorge: Wow, easy? I book it now!
