A bug

A bug on rug is who I be ,
sometimes in a house and sometimes in a tree
sometimes on a couch and sometimes on
the floor where human beings see me and
scream for help forever more
I have a family just like you
they love me dearly yes they do
but to day I like to mess with you
just to see what you would do
I don;t know why, I see you everyday
I guess I want to see the look on your face
when you say shoo and go away
ok, I move but yet I come back another day
