Просто надо кровать побольше.

Даже незнаю, чего хочется больше, спать с таклй вот красавицей или в обнимку с пони?

Is hugging an “action“ performed in this picture? Yes! And it is interchanged, also returned, by lifeforms of different kind, also known as interspecies. One lifeform, lets call it P, doing actions on the other one; we will call it H. By changing the sides in this equation and adding the first statement it resoles to human on pony action.
 
But does this interpretation of the formular really show the answer to what is happening? What is the author telling us as the quit, thus commenting audience. Is the creator impliing something or just tricking us to belive something already happend?
 
Please write a short text about what we don‘t or can‘t see inside the frame of this artwork. I will collect them next week and grade them. Class dismissed!

removed the ”human pony action” and ”interspecies”. There’s nothing of the sort in this image.
