playing bumper cars with the grim reaper

i have a coworker who i enjoy talking to and who is often good for a humorous rant and sometimes too good for a not-so-humorous rant. i've come to realize that talking to him can be a lot like bumper cars, which can be quite enjoyable if you do it very infrequently but could be quite tedious if did it every other day for years & years. so the realization i've had is that he's actually trying to bump cars, not deliberately, but unconsciously, which is a metaphor of harshly arriving at the conclusion he has already assumed, and thus, the collision. the game for me has become trying to avoid the depressing tedium of bumping into the same conclusions over & over again by asking questions that, if not avoiding the bump, at least extend the swerving time longer. or maybe the realization is that coming to a conclusion rhetorically is just driving closer & closer to death, and that every conclusion is a little death of the mind that inches me toward an absolute conclusion. questions are what keep the door ajar. questions keep me filled with breath.
