It’s only after three weeks into a new job that I made a serious mistake. My boss called it “extremely embarrassing” in a company-wide e-mail — which,    31  , he wrote because he felt he needed to explain that what I did was something    32  in the company should ever do.
I wish I   33   give a good excuse for what I did. At the very least, I wish I could explain it somehow —    34  it on youth, inexperience or ignorance. Unfortunately, I’m    35  , experienced and I know better.
   36  I work with some very kind and compassionate(富于同情心的) people. For the past couple of days many of them have taken time to   37  by my desk and offer comfort, encouragement and support. Some have shared with me similar    38  they have made. Evidently I’m not the only “    39   ” person here.
One of the exchanges I had this week was with Lois, the much-honored, much-respected professional who    40  the desk right next to mine. Lois was completely    41  about her work, and to be honest I was a little nervous about how she would   42  to such an extremely embarrassing incident.

“It happened”, she said, “There’s nothing you can do to    47  that. It happened. But it’s over now. It’s   48  . It’s in the past. You need to let it go, and move on.” And with that she returned her   49  to her work, as if to say, “We’re done here.”
I beat myself up for weeks. At such times I need to remember those   50  words: It’s over. It’s done. Let it go. And mostly, move on.
