Poem #4 Who/ What am I?

I know everything about you,

what you are doing and when 

every day, month, and year

I am your plan or your change

All day all night I sit

motionless. Physicals, but mentally, 

I know that you use me

I could be as blank as a page 

or as colorful as a rainbow 

on me there could be cats, dogs, of flowering grass

What am I?
