can u say something remotely intelligent please?

have u ever been in a conversation whereby u feel like a dumb blonde (i'm not stereotyping blondes here, really, as most of my blonde friends are actually extremely intelligent)?....the thing is, i always always feel extremely brainless in every one of my conversations....reasoning?...ah, coz i never managed to be coherent, never come out with an original idea, never seem to have a justified opinion, never utter any witty comeback, or in plain words, i sound like an idiot uttering nonsense just to get things going...some of my brilliant comments:

• mr. X: 'i think our new prime minister needs to put more effort to be more accessible to his constituents and to think fast on his feet...nowadays, it's really hard to fill mahathir's shoes, no matter what ur political leanings are...'
• me: '........................................................................................' (thought: shit...whatever does he mean???...new prime minister???...political leanings???...da da da...i'm in the twilight zone...da da da...)

second conversation:

• miss x: 'to think logically, we can't always be neutral and non-judgmental...we are human after all...we must sometimes stand firm and say 'i agree' or 'i disagree' and justify our belief...i believe in liberty in religioun...no blind faith for me...'
  
• me: 'errrrrrrrrrrrrrrrrrrr........hmmmmmmmmm...'(after 30 painful seconds) 'did know that ricky martin is gay?' (note: after all, what can be more eloquent than that?)
  

when have i fallen so far from the Eden of great repertoires and knowledge?...have i even been there before?...it's a major relief that i'm not blind to my stupidity but it's no great relief to know that it's incurable...i have absolutely no understanding in human psyche when it comes to live conversation...my only and best solution so far: either i buck up (read some more, u moron!) or i deserve to live in the dark, with my room's 4 walls, and yes, u too dear dear bloggie, as as silent yet loyal companions....end of self-rumination of the hour/day/month/year (which ever u prefer)...
