I was assembling a large printer by myself. Lots of parts, needed a forklift to get it on a stand and a lot of work to prep it. I was there for 5 or 6 solid hours.
I was in a secure building and had to sign an NDA - and technically was not allowed to have my phone or even bring my water in there.
So I'm in this large room and they have desks spread around. Big area with shiny concrete floors.
This lady at one of the desks was listening to Pink Floyd. She was humming and kind of vocalizing the music, but not the melody like normal people do. She was humming (and she sounded like Rosanne) the "noise" and effects/synth parts of the songs.
I was hearing here making these noises and it was really pissing me off. I was concentrating and working and she was fairly loudly making these noises, like "boing boing boing" and other weird noises. I didn't even know what the hell she was doing for awhile until I sorta made out that she was following along to the songs.
She obviously knew the songs - but she was humming along to the keyboard parts and noises.
God, that went on and on and then she finally left for lunch.
