My personal favorite is that he heard the 'intruders' because they slammed the toilet door. Really? Intruders slam doors when they break into your home? Why not just break down the front door if they were going to be that noisy, why bother climbing though a window and then slamming a door to alert the residents. Ridiculous.
Agreed, and it was utter foolishness to have introduced the 'slamming' word .. but I doubt very much it was intentional, it was a slip up as to what actually happened that night, as was the 'kicking' of the toilet door when OP slipped up once again when he something about that door not only being slammed but kicked at the same time, as well. OP thinks he has total control over the trial and what he says, but it's not possible and little words like this will keep on slipping out ..
