Small world

The world I say's a tiny place
there aren't a lot of people here,
we know, from travel far and near,
we'll always find a well-known face.
I cross the sea, I've left no trace
of where I was, the ground is sere,
and yet I've come upon friends dear
whose travels also match my pace.
I never know from where they'll pop
but they are there when I turn round
surprised but still with cheery hail.
I have a feeling it won't stop
until my body's deep in ground
or else when all of life must fail.
