Okay, I really shouldn't wear the same clothes two days in a row. It's not so much a fashion problem, although, I'm sure latraviata, Judge Dredd of The Fashion Universe, would have my head for it =).
I get into the office at about 0900h. Most people bumble in around anywhere between 0930h to 1000h. The earliest I leave the office is 1930h. The image then is that I'm at my desk when they leave and I'm at my desk the next morning when they arrive. If I'm wearing the same clothes two days in a row, they think I stayed at work all night.
Some people work at home. I live at work.
