Shyness: Two very different perspectives to the same situation.

This describes me perfectly!

If you're the person on the left you might think that I'm an incredibly boring, untalkative, 'antisocial', stuck-up, kind of guy.

If you're ME, the guy on the right - this is what's happening: suddenly, your mind's gone blank. You have many wonderful ideas, and thoughts regarding what she just said - but suddenly, all of that has just rushed out of your mind. You feel like you're now staring at a blank piece of paper. Meanwhile, time's ticking by rapidly - and the social imperative is that you give an answer. So you hastily say a "no", just to show her that you did not ignore her. You continue to try to think of what to say - but you can't. You just can't, it's like staring at a blank wall. Finally, the other person gives up. The other person leaves, and suddenly, everything you could have said, comes flooding back in.

The same situation.

Two very different experiences.
