I remember what my supervisor said to me when I did my internship in Tokyo.
I overslept and came to the office late. I apologies to my supervisor, talked to him directly and sent him email that I was feeling so bad. And this is his reply:

Well, you don't have to apologize to me, rather than to your self.
This is "just and internship, but if you actually start working somewhere, it's those daily actions that will determine how your colleagues/clients will think of you.
One of my former managers used to tell me "Building up trust takes a lot of effort over a long period of time, but you can lose it at once with just one or two mistakes".
I also oversleep sometimes (almost everybody does now and then, we're humans after all), but you've done it almost once per month now... that's a bit too much for our taste.

Yes, I came late to the office almost 3 times since I started my internship there. At the first time, I came late for 5 minutes, second time for 2 minutes, and last time was the third time for 1 hour.
But what I want to say, the way he treats me can make me feeling so disappointed to my self. I promise, it will not happen again.
