4. Make an Apology:

If your mistakes did harm to anyone, you should make an immediate apology on what happened. You may send an offer letter to a wrong person. If you realized your mistake, you must say apologies for that. And, remember that for one time people may forgive but if you do the same mistake again and again, you will be ruining your career either. So, you should ensure yourself that you will not commit such mistakes again.

5. Go on:

Getting back to a normal day as usual will help to leave that incident as a least memorable one. If you are unable to focus on work, try to read some interesting things, or watch something interested. Playing your favourite game or listening music can get you back to the normal heart beat. It is better to prevent yourself from focusing on that embarrassing moment and it can keep your day fresh and bright.
