"You think you know, but you have no idea.."

I'm full of questions.
All the time.
It makes me mad sometimes because it reminds me of a kid me and my childhood friends knew who asked questions ALL of the time. And they always seemed to arrive at the most inappropriate moments. Moments which, in actuality, didn't exist at the time in my 12 yr. old world, it's just something we boys used to conjure up. (Example: When trying to lie to our parents about how far we were walking to the "store", our inquisitive friend would ask loudly, "IS THERE EVEN A STORE IN THAT NEIGHBORHOOD??"=inappropriate moment) Obviously, there was no "store", but in fact some girls we wanted to visit.
But I digress.
The question at hand is, do you ever think you know it all? I mean, up until 'that moment'? Or do most of us just wing it from day to day, ascertaining our 'facts' for tomorrows discoveries? And I'm not talking about the "idiot-know-it-alls" we've all come in contact with, I mean those of us who are tired of ambling through our lives because we thought we "knew it all"..

I'm going to try to pare down the amount of questions I have a day by just ignoring them. Simplify.
Then maybe those headaches will stop.
