Hard, Hard Problem

Hard, hard problem:
You turn it over
Study it from the other side
Push it around the floor
Bend it, but it springs back
Gnaw it, until your teeth hurt
Try one thing on it, then another
Set it aside
Pretend not to care about it
Sneak up on it and surprise it
Trade it for another hard, hard problem
Take it back again
Carry it with you wherever you go
Sleep with it beside you
Wear it like a collar
Wear it down
Weary it
Worry it
Dirty it
Clean it
Chew on it
Find a tiny crack in it, maybe that it had all along
Make the crack in it a little larger
Give it to the next dog
