Left in the cold

Dumped in the cold
uncared and old
I stand in the hope
when the snow melts
in the summer sun
my roots shall be watered
and there shall come up
new leaves and flowers
and a passerby may rest
under my shade
and when he leaves
he may remember
there was a tree old and big
but alone on the way
that gave him shade
when he needed it most
and saved his life
from a heat stroke!
