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 desk and chair 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.
最后要说的是，办公室今天晚上会粉刷涂料，这样经过一个长周末就能干了。如果你们有东西贴在墙上，比如海报、公告牌、照片等，请先将它们取下来。如果你们有较大株的植物，最好先把它们放出去，以防洒上涂料。办公桌和椅子不会有问题，因为刷涂料时会在上面蒙上单子。如果你们需要额外的单子可以找我，但是单子的数量不是很多，最好将你们所有的物品都拉倒两个单子下面。墙壁的颜色还将和原来一样是黄褐色，但会稍浅一些。感谢大家的时间，希望你们都度过一个愉快的周末。下周二我们在新粉刷的办公室再见。
