a walking billboard

On Friday, I bought two boxes in order to start shipping things home (mainly books and clothes). I carried them flat in a large enough bag that fit them, in my armpit like it was some sort of artist's portfolio, from the post office to the record shop to the grocery store and finally to the bus station. It wasn't until I got home that I read the Post Office's slogan on the bag: "For the little things that make the big things happen." I laughed as soon as I noticed this. I carried that stupid saying all around town? I thought.
