it has to be out of habit... (if you picture the words 'my anger' from the title to the secondary title to the poem, you can picture a car getting smaller and smaller. maybe its just me) thank you for commenting!
I can see what you meen. I just saw it as two titles and the beginning. Also an old talk on dp is, if the ttle is the beginning of the poem would it not be enough with the first line in the poem so it reads. My anger . then starts with Is a speeding car
