premise: A BMXer biking off of ballets leaned up against a fence. hypothesis: The biker is taking a break after practicing his moves on his bike all afternoon.
neutral: Just because there is a BMXer biking off of ballets leaned up against a fence, it does not necessarily mean that the biker is taking a break, or that the biker was practicing moves, or that the BMXer is a guy practicing his moves, that it is anywhere near afternoon, that the bike is even his bike, nor that he has been on the bike all afternoon or even at all.
