Hi Person 2,
I'm writing to you today to ask a favor. I'm in a bit of a jam and I was hoping you could help me out.
Of course, what can I do?
I need you to write a letter for me. It's for my boss and I'm terrible at writing formal letters.
No problem, I'd be happy to help. What do you need the letter to say?
I need to ask for a leave of absence. I'm going to be out of town for a few weeks and I need to make sure my job is protected.
Okay, I can do that. Can you give me a few days to work on it?
That would be great. Thank you so much for your help.
No problem, I'm happy to help.
I really appreciate it.
So, I'll just check back with you in a few days?
Great, thanks again.
