Dear Christopher
Chris, I feel terrible that I didn't say anything on here about your new job. You went away on training, and I haven't been on here. I didn't mean to leave you out, and I just wanted to apologize. I didn't do that on purpose.
I know you're feeling a bit out of your comfort zone right now, but you're so good with people, you could sell anything. I know you'll be very good at your job once you settle in. This may lead to other things down the road, but I know you'll succeed in this position, and I know you'll enjoy it.
I hope your first week wasn't too gruelling.
Talk to you soon.
