[Ultralomaniac]

Consider it like this:

You and i are playing a friendly game of go-fish at my kitchen table, drinking some orange juice

then you start throwing punches at me out of nowhere
and i block them and punch you back, actually giving you a black eye and breaking your nose. you then file charges against me, but it was in self-defence so you have no grounds. i drink your orange juice then never speak to you again
