Fishing?

Bert says so. Someone on a Facebook asked me if I would like to sell the drawing I have made.  At first I was thrilled.  I mean,  who doesn't want to to get payed for ones hobby? 
Then Bert said, that's not a serious buyer, he wants something from you. 
We each started Googling and found several photos of the person in question and several places of residence in various countries. 
My enthusiasm has disappeared, but everyone on Blipfoto can look at it for free and that feels good too.
