June 31st is the easy one......The spiral-bound book on the desk opens the wrong wat around BUT this not might not be true for the Chinese!.....The desk is rubbish, you can't get your legs under it and the word 'Math' should be 'MathS'....that really annoys me!
As for the cup!! If it were a left-hander drinking it, the cup would correctly be on the left, but so would the handle. If a right-hander, the cup would be on the right-hand side of the computer with the handle to the right (as you look)....THe wall looks like a lmainated floor and the keyboard is a mirror image.

You have really upset my OCD today with this terrible picture so please get back to some real maths tomorrow!!

Thanks for the fun and best wishes for a great weekend :-)
