Polling for six year olds

Yesterday my six year old cousin, Walter, abruptly asked 'what's your job?'

It kind of stopped me cold. How do you explain polling to a six year old?

I told him that my job was to find out what people think about things.

He paused, gave me a quizzical look, and then said in a voice filled with incredulity, 'someone pays you for that?'

Didn't really know how to respond to that one. It was pretty funny.

If you know of a way to explain polling to a six year old that will make sense to them let me know!
