I respect the tone of this blog post. I pause to think how I would word this experience if it happened to me. Since it hasn't, I don't really know how I would react. However; having this cool composure to think through why things ended up as they did and how it could be improved in the future is something I hope to aspire to.

The ego is one helluva thing, and a hurt ego with negative self talk can lead one down silly paths. OP is cool as a cucumber.
