The John Lewis Window Display: Anyone Notice the Problem?

Can you tell which side is the boys toys? And, which side is for the girls? Because, personally, I really struggled with this since I did not know that only boys were allowed to play musical instruments. I already knew that girls weren't allowed to like science experiments or lego and that we were only allowed to play with dolls and prams so we didn't get confused as to the exact purpose of the uterus but I totally thought we were allowed to play the piano. After all, Jane Austen was forever droning on about young girls being taught the piano in order to be "accomplished". Have we lost the right to do this too? Was there a memo I missed? Should I donate our piano to the nearest boy in case in makes my girls grow a penis?
