Помогите плиз надо составить диалог на английском например : Masha:hi!where we're you...

Mrs S: Excuse me, can you help me?  Shop Assistant: Yes of course, what can I do for you?  Mrs S: I bought this T-shirt for my son this afternoon, but it doesn't fit him, it's too small.  Shop Assistant: Do you want to change it or get a refund.  Mrs S: I'd like to change it for a larger size. Do you have these in large?  Shop Assistant: I'll just check. Let's see, yes we have large or extra large, which would you prefer?  Mrs S: I think large will be fine, it's for my son.  Shop Assistant: That's fine, if it doesn't fit just bring it back again. If you take it to the customer service desk, they'll sort it all out for you.  Mrs S: Thank you. Just as a matter of interest do you give refunds?  Shop Assistant: Yes, of course. You can bring any clothing items back up to three weeks after purchase, but you must keep the reciept.  Mrs S: I see, thanks again.  Shop Assistant: You're welcome.
