John,

The Character 'David Brent' is an interesting one.

He has no idea in his head that he is anything less than funny, dynamic, intelligent, exciting and a real winner.

He is the kind of person who might be embarrassed by "social inadequates".

He would restrain his laughter at such people, but his instinct would be to laugh at them nonetheless.

He would recognize no "socially inadequate" characteristics in himself but rather wriggle out of admitting his own flaws with a combination of denial and projection.

In fact, he is very insecure and overconscious of how he is perceived.

Ultimately, he proves to be a nice guy underneath.

Its something most people can relate to in themselves - I wonder if you see any parallels with your life?

This is ultimately the result of his own insecurities.
