We all make mistakes, but every now and then, an error of judgement has huge consequences for other people.
Life is precarious and unpredictable. We cannot foresee all possible outcomes, and things can happen over which we have little control. But one small error of judgement, such as thinking you’re sober enough to drive when you are not, can have enormous consequences for other people. A mere apology cannot undo the damage that is done. Sometimes what you don’t see can hurt other people badly.
So take care, watch out, and keep your eyes on the ball of life. At all times.
