Man Beats Up His Friend? Ex? While He's Still On The Toilet

We added question marks because we don't know whats going on here.  What we do know is people normally only stand in a bathroom while the other person is taking a dump if they are in love or used to be.  I've been mad enough to want to hit a few folks but not mad enough to do it while they are still sh*tting.  And why didn't ole boy wash his hands or wipe?
