An Interesting Character

Where does one find such a thing?
Everyone wants one
Wants the power to be one
Or invent one
Everyone knows one 
Or many or a few
Although almost no one
Has one under control

I saw one down in a well
When I was little enough
To be one myself
I thought I could make my own

I wish I could bring it back 
Into life now, I wish
I could wrap it up to sell
To other well-wishers

Who would only buy because
They were still wishing
To capture one to sell themselves
