Oh My EARS

The space across the hall from my office is being renovated for another department which is fantastic, however, they started construction this morning and they're using a "floor grinder" which makes it sound as though a plane is about to land above my office. I have never heard a more terrible noise. It's been going on for about 3 hours now and I have ear plugs in. They are estimating being done in three days. Have I mentioned how happy I am about not working Friday and only working a half day on Thursday? And this is our department's busiest week every month. Holy Buckets!!!!
