Something I've learned from raising children is that the behaviour patterns the children follow are ultimately the same behaviour patterns us adults follow too. We just like to pretend that we know better or have overcome the childish instincts, but in many cases we have not. We act exactly same way and then come up with some bullshit excuse for it after the fact that makes it seem like we are not exactly the same species of monkeys acting on instincts like our children are.
