Theme: the feet

Have you seen feet like these? Do you think it is easy to control all of them before take off and landing?

Subliminal message

This photo is displayed in a primary school in public area. It clearly conveys a message a child can not consciously analyse. You might read it differently, but for me the photo says - you will fail to free yourself and will stay behind the bars. "Behind the bars" interpretation is particularly interesting to me and could go further - it could be a system, a school itself, a freedom of choice and so on.
