Answer:
I am bought by the yard but worn by the foot
I am the outstretched fingers that seize and hold the wind. Wisdom flows from me in other hands. Upon me are sweet dreams dreamt my merest touch brings laughter.
If you lose one of me, you are upset, bewildered, and perplexed. If you lose two of me, you are blissfully unaware. What am I?
Brown I am and much admired; many horses have I tried; tire a horse and worry a man; tell me this riddle if you can.
Of these things - I have two. One for me - and one for you. And when you ask about the price I simply smile and nod twice.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
