Could just be seperating the parents from the children to show that because of the choices they made their parents no longer speak to them and only symbolize what little of a relationship they do have through ah fucking sticker :p
I'm all about being honest and things, but seeing a "my stick family" of 2 people doing doggy style is slightly awkward. Especially when I have to explain it to my 6 year old cousin -_-
Sounds like a fanfiction to me
