Have you ever noticed lines? No, not lines that you wait on. Just lines...
plural noun: lines
1. a long, narrow mark or band.
a length of cord, rope, wire, or other material serving a particular purpose.
If you don't know what I mean....or you just think I'm plain crazy (half-true!), visit the local playground. Look at all the lines. They are everywhere. Curved lines, straight lines, diagonal lines, lines leading to other lines. I especially like it when my little is among those lines. Placing a human figure among those lines, strengthens their appearance.
And then there is the occasional Police Line (you'll have to scroll down to get this...)
