BOY MEETS ONE OF THE WEE FOLK

Cryptozoologist Lars Thomas in his book Curious Encounters tells of a boy in Iceland who would go fishing.  He would go fishing on his own but, after 5-10 minutes, he would look across to the other side of the body of water (pond, river, whatever) and see he had been joined by one of the Wee Folk.  If somebody else came by, the Little Man would put a finger to his lips and disappear.  He never conversed with the Little Man.
