Change of address

So I just got back from filling out a change of address form for our former bureau so that the late-breaking news contained in the mail we used to get (that's a joke) will be forwarded to the main office.
It occurred to me as I was carefully printing inside the boxes that I may be doing it wrong.
Are you supposed to leave spaces or just run the letters together?
I left spaces, but I wonder if it is going to be "processed" by a human or a machine.
Forms scare me sometimes. They're so...form-al.
I guess I am afraid I am going to make a mistake. In pen.
Other things that scare me sometimes are open spaces, high places and NASCAR races (sorry Michael but it rhymed).

Things that scare me all the time include closed spaces, examination rooms with no windows, MRI machines, any room without windows, and snakes.
