Jamal, I hope you get this before you get home. I need you to pick up some fish from the market since it’s next to your office. Get whatever you think looks good. I’m getting off work a little later than I expected, so please start the grill when you get home. Everyone will come over around seven, so we should have enough time. I’ll try to get home by five, but I’m stopping by the store to pick up a few things. I put a pie in the refrigerator, so please get it out and put it on the table. Could you also please clean up a little before our guests arrive? Thanks a lot for your help, and I’ll see you soon.
