Wild Family of Forest Folk.

Do they travel in family groups?  Do they meet up from time to time with other groups. Do they Stay underground or just in the woods but out of sight, all of these question i have been asked and the honest answer is i dont know!!! There must be more than one group in each area, how do the stay hidden so well? We find their signs in the woods and puzzle over the meaning. We gift and leave food in the hopes of making some kind of contact, all to maybe have a chance at getting answers to these questions.  I meet witnesses after witness who all have the same question and more. One day we may know the answer to some of the riddle. but for now we just have to continue to search, and hope.
