What Year is It?

On any given day, I have absolutely no idea what year it is.  Sometimes, I think it's still 2007.  Or, maybe 2010?  I get confused.  Probably because I work on so many stories at a time in different years and seasons.  For instance, today I had a photo shoot for summer 2013 and holiday 2012.  I love how random my days can be.

And speaking of random, I spotted this sign while on my photo shoot and can't really understand it.  Perhaps it was relevant when the studio was first built (it's a white room studio which means it's supposed to stay white and clean and the floors don't have corners to avoid warping in drop out photography).
