Dear SARA BROWN,
Unfortunately, I need to inform you that I will be absent from Monday’s training seminar. I am in the process of relocating for the job, as you know, and the flight I had intended to take up was booked. Consequently, I am taking a later flight and will be arriving too late to make the meeting. I will, however, be in attendance on Tuesday. I look forward to this new position and learning about everyone I will be working with.
Thank you for your patience in this matter. If you need to reach me, try my cell at 555-555-5555.
