Let us be glad for tangled things--
   For soiled fingers raking thick-stemmed grass;
     For matted fur on long, warm ears; 
Or child's hair idly twisted in rings.
   A thatch of ganglia fires in the brain's wet mass:
     A thought--electric--splits, connects, adheres.

All things rooted, snarled, or tensed,
   Whatever needs some mesh to form its mass,
 With loops, forks; twists, knots; ends, tears.
   Let's give thanks for things that are soft and dense.
