Dear Austin Parker,,
You are required to submit directly to me or through my secretary the complete February inventory by 5:00pm on Friday. If you run into any problems that will cause you delay, you need to speak to me on Thursday morning at the latest. I appreciate your cooperation with this.
Sincerely,
Aaron
