In a split second...

Does one embarrassing moment destroy all the coolness that a person has built up over the course of a relationship?

I've always acted professional with my advisor, presenting a cool exterior. Well, today all that hard work went down the toilet.

As I was leaving his office, I swung my rather heavy backback over my shoulder. As I was doing this, my cell phone that I had forgotten that I had placed on top of my bag flew to the ground. As I turn around to see what fell, I lost balance and pretty much fell on the chair. It was really embarrassing as anyone would be able to tell. It was at this moment that I felt I lost something in how I presented myself to my professors. It was a goofy mistake which I'm sure I'll laugh off in a couple days, but as I'm typing this post it's the most embarassing thing I've ever done!
