I Stopped by the Store for a Stamp

It was on an icy morning when I hurried back inside -- To grab my coat and money -- Then I scurried back outside. I walked along the sidewalk while (Beside me in the shallow snow) My shadow shook; it slyly slithered To escape my sliding toe. The little shop was almost empty, But I knew it wasn't closed: The people must be back at home, Not wanting to be froze. I bought a stamp and stuck it on The outside of my letter -- To send it to my oldest friend (Whose friendship just gets better). His parents didn't want me there (Inside their house, I mean); I had to leave 'cause I was different (And make new friends, I mean). And so I sent the letter, And I hurried on back home. But I don't know why it's like this, Beneath this snowy dome.
