3 made me laugh (maybe because I felt the same way about Los Angeles), and no arguments over 9 and 13. As for the profanity: in some workplaces it’s almost mandatory. Some. Not all.
I have no idea where this photo was taken but I think probably somewhere in the US. Why so? Well, no Australian in their right mind would let a roo loose in an office. Even a baby. They’re not fun or cute when they start kicking.
Also the source uses inwestphiladelphia as their moniker.
