A lot of trouble could have been avoided

Because it's staring you in the face I suppose it's harder to resist the urge to play it. An analogy could be drawn to a guy who likes to snort coke but knows it is against his own best interests to do so. He also knows he has a harder time resisting the impulse to snort coke if he is staring at a pile of it for an hour or so than if it is not in his site. Out of site out of mind so to speak.
