okay so wait...the snowball thing...you gave me a preemptive 'duck'. therefore i was warned. so how do you know if you hit me or not, cuz i may have a fast reaction time. hmmm, never thought of that did you! yeah that's right.
so...there is no knowledge of whether or not i was ACTUALLY hit by said snowball, therefore it can be disregarded, as we know not the outcome of the event.
see, it's like a bad polynomial equation!
shmack!
