I had one of those above me when I was working. Finally, at 0230 one morning, I went upstairs, knocked on her door and asked her to please not vacuum at that time.
She had no idea she had a downstairs neighbor, and was awed when I told her I had lived there 13 months. That was the end of the nocturnal vacuuming. ;o]
That never occurred to me!
In one apartment in San Antonio, we called the upstairs neighbor “The Man With the Cement Shoes.” Fortunately, he didn’t keep weird hours ;-).
