Working day after New Year

All offices of the school reopened today after New Year holidays. It was abuzz with activity. The parking lots were getting filled soon. Some of the workers were working on the roof of my office building. I guess they were fixing shingles. They didn’t even demarcate the hard-hat area. I noticed some shards below. Anyway, I am not able to concentrate on my work with the banging sound right on top of me.
