Who needs confidence when you can have fun instead. Being geeky usually means you get more pleasure from simple things in life like your geekisms, something lots of confident people lack !
But try chatting with a girl during a punt and trying to explain to her "My god how can you not have heard of The Princess Bride, its the best film ever. it stars Carey Elwes from the first Saw movie.
Then its my god, how can you not have seen Saw. Everyone has seen Saw. Well then the Princess Bride also stars Mandy Patinkin from Alien Nation and Homeland.
And then Jesus Christ how can you possibly not watch Homeland its brilliant and its got Claire Danes from Terminator 3 in it too as the star. Then its what were you doing during the 80s and 90s. How can you not have seen any of the Terminator films. Its like required watching.
I have had this exact same conversation so many different times with WGs.
So basically getting pleasure from the simple things often makes you look a bit nutty and eccentric to people not on your same wavelength of thought.
