Who's afraid of a ghost?

Who’s afraid of ghosts?

There they are driving in my almost new car,
sleeping in my bed and using my computer,
they have no shame. I’m angry but can do nothing,
I’m dead and so pathetic that they don’t even see
me when I walk through the house as a ghost.

I have met other ghosts around here they are
a wretched lot, can’t let go of things they had before
and can’t take with them wherever they are going;
so they hang around full of envy hoping the world
will collapse around the ears of the living
