听力原文：Finally, the office will be painted tonight so it can dry over the long weekend.

If you have anything on the walls such as posters, bulletin boards, or pictures, you will have to remove them. It might be best to put any large plants you have outside, so they don't get paint on them. Your desks and chairs should be fine, because there will be sheets placed over them. If you need an extra sheet, please let me know, but there aren't many, so you'll have to try to put all your belongings underneath the two sheets. The walls will be the same tan color, but a shade lighter. Thanks for your time. I hope you all have a good holiday weekend, and we'll see you back in the office with freshly painted walls on Tuesday.
