Well, since the basic act of philosophy is finding answers to tricky questions, I thought this little gem of traditional culture would fit in greatly here.
Rules and guidlines:
One user asks a riddle of any chosen complexity. It must have a right answer, and it may also have other, technically correct answers. Riddles go in level 1 posts. All guesses go as direct replies to the riddle post. "Correct"/"wrong" goes in the reply of the guess. Let's keep this neat and tidy, k? Also, no limits on times guessed or number of guesses in a post, just try to refrain from wall-o-texts.
So, here goes my first one.
Roars like a bear, stands like an oak, feeds like a mother. What is it?
