My name is “Patch”

Looks at me
I’m sad right through
I try to smile
but what can I do
no one loves me
not any more
I was kicked
right through the door
I love people
I love them so
But I’m now alone
as well you know
my name is patch
and I’m in a hole
no one around now
to console
Christmas could be the end of me
its come over here where you should be
a little injection
and the lights go out
its rainbow bridge
you will hear me shout!
