Some desperately need to say who they are, and say that they are good, and need to say that they are someone... The nobody does not need that, and that's a hint for the name "nobody". He feels no need to affirm his presence, he feels no need to tell people who he is, but this way people dont realize who he is... even when he is telling it to them...

Funny, dont you think?
A funny world indeed...
Peace.
