Regret. Sometimes it sneaks up on you from behind. Sometimes it sneaks up on you from behind and then slams right into your heel. Regret. Regret is allowing your 8-year-old and very enthusiastic son to push the shopping cart. It does not appear immediately. Not even after the first time he runs into your feet from behind. Sure, there are some early inklings of regret, but not a full-fledged “I really should not have done that” feeling. Then it happens. You can hear the shopping cart accelerating behind you. You hope he has control. Then you feel it. That sharp impact as the cart slams into your heel for the second time.

Regret. It can also fade away, as you become thankful that you were wearing high impact loafers.
