Annoyances

They are doing construction on interior of the office's back entryway several floors below me. They're using some sort of grinder to clean the floors before putting the tiles down, have been doing so all day.

It is driving me up a wall.

My office is directly above the entryway, and the sound (a pulsating squeeking noise) is resonating through the stairwell and into my office.

Hopefully this will be the only day it's running.
