In the poem crossing willow bridge by lorna crozier,explain what is implied by the words,"Our walk becomes a journey".what two devices are used in...

The walk the pair, or group, if you include the dog, take
in Lorna Crozier's "Crossing Willow Bridge," proves to be more than just a simple
walk. 

The mother, "seventy-six/this year," has recently
become "unsteady/on her feet."  The dog, a black lab, "All energy and muscle/and too
much love," bumps the pair's legs and smacks the mother's legs with the stick. He makes
the walk difficult.

Instead of a short, easy, leisurely
walk, then, the walk becomes a trek, a journey, difficult and risky.  The mother, being
unsteady, could easily fall on her own.  But the dog makes the possibility that much
more likely.

The speaker also sees the dog as having "more
to do/with time, how it runs ahead and keeps returning"--the dog, literally, and time,
figuratively.  Plus, the pair walks over the bridge, then back
again. 

The difficulty, the running of time, going back and
forth over the bridge, all combine to make this walk more than a walk--they make it a
journey.
