nine
o'clock
We can keep our lights all night if we choose , the only requirement being that we do not disturb others -- we are not supposed to entertain on a large scale . The result is a beautiful commentary on human nature . Now that we may stay up as long as we choose , we no longer choose . Our heads begin to nod at nine o'clock , and by nine-thirty the pen drops from our nerveless grasp . It 's nine-thirty now . Good night . Sunday Just back from church -- preacher from Georgia .
