Sonya: Hi, I heard from Anna Davies that you've joined our team. I'm from the AE (Audio Engineering) branch and every so often we'll be needing you for our recordings. At the moment, we only have two recordings needed for British English, but I think it's a smart idea to become familiar with the equipment as soon as possible. Therefore, I was wondering whether you could tell us what hours will you be at the office, so we could plan things out. All the best, Sonya Bennet
Adam: Hello! For now I can declare that I'll be definitely be in the office on Thursday and Friday - I should be there tomorrow and on Wednesday, but right now I can't state exactly when.
Sonya: That's alright, we don't have to declare exactly when to meet - I'm in my office everyday.
Adam: Okay - I'll let you know when I'm at the office. 
Sonya: Sorry, I should have aksed. Can we say "you" to each other, rather than Mr Jones?
Sonya: *asked
Sonya: Great, I'll send you more instructions when you arrive.
Adam: Of course! It's not a problem :) 
Adam: Okay, we'll be in touch.
Adam is joining Sonya's team. She wants to know when he will come to the office. Adam will be there on Thursday and Friday, and maybe tomorrow and on Wednesday. Sonya is going to send him more instructions then.
