I am not completely sure what you are asking. If you are asking how to open and close a topic about your horrible/embarrassing day i would start out with something like this:
Sample of one of my embarrassing stories and how i started it:
The smoke had filled the room by now, it was on the verge of expanding but the wooden door held it back. The microwave was still following the command i gave it when i hit the 2 minute button and pressed start. I had walked away for a second; i needed a clean spoon and i wasn't about to use the ones in this room.
That is actually the middle of what had happened to me. But i put it in the beginning since this is where all the action(action or climax of the story) begins. Its more interesting instead of saying:
Today, was one of the worst days of my life. See, you could say it started out normal, even great. But it ended with a feeling of embarrassment that invaded my whole body.
That would probably be fine. But start with the meat of your story. Tell a little bit and than go back add your beginning a paragraph down. That way your reader is engaged right off and will be more interested in what you have to say.
As for the ending, try leaving it a little bit of a mysterious. Dont end it saying that was the worst day ever.
Try ending it like this:
As for the cup of noodle goes, somethings are better left for the experts.
Its not a cut and paste ending.
