Let's make this very simple

Ok, let's take this very nice and slow for you: Sometimes when adult speak to each other they say things in a way that almost seem like a lie because they don't really mean exactly what they say. It is like when your mom calls you her "cute little retard". This does not necessarily mean that you are cute. She just says that to make you feel better.

Now, sometimes when adult speak they use an "adult speaking method" called Irony. I-R-O-N-Y. When they say something with irony, they don't mean exactly what they say, they mean quite the opposite! You are supposed to understand that they mean the opposite when they use this ironic adult speaking method. Otherwise you are just a stupid little retard.
