Living in the dark.....spooky

What do you think when you first look at the title ?
Ghost story ? My life as a dog ? Fear of darkness ? No..it's not about that.

When I wake up around 6 or 6:30am and get ready for my 8am shift, it's dark outside.
When I finish work after 4:30pm and get ready for dinner or to go home, it's dark outside.
When I wake up on a day off like Sat but I work overtime, again, it's dark outside.
And people in the office at the control centre (who monitor us), it's dark (shady) on their faces too.

Thanks for calling xxxxx, it's still dark outside (Ooopssss! ^~^)...... can I help you ?!
