Our mission today is to find the nearest Likely Human Candidate. Approach your Candidate with a pencil and a clipboard, although a notebook will do. Holding the pencil at the ready, inquire:
"Excuse me, I was wondering. What was your favorite tree growing up?"
(Now we need to wait for an answer. This is the hard part, but do not skimp.)
One- one thousand, Two- one thousand
Carefully scribble down the answer, and thank your Likely Candidate. You might need to offer a word of encouragement.
Be prepared to improvise, since your Candidate may wish to carry on.
Congratulations, we have just shared a precious splash of childhood.
