If you have ever heard a car engine backfire, you know it’s abrupt and loud enough to send cats leaping vertically into the air, jolt sleeping babies awake, screaming, and cause soldiers who struggle with PTSD to ‘hit the deck’ cowering in fear. And if it’s something your car does, or maybe a close-by neighbor’s car...one hopes the problem is fixed sooner than later. Suppose you do have a neighbor whose car develops this obnoxious problem and they apologize to you for its unruly disturbances, informing you they are taking it to a local garage the next day to have fixed. Then, a few days later while enjoying your first cup of coffee that morning, you hear that neighbor getting ready to leave out for work, or maybe to church and as they pull out of their driveway...there goes the loud explosion of their car backfiring once again. It causes you to recoil, spilling coffee down your front, as local dogs in the neighborhood begin barking loudly. Maybe it happens one more time...
