Sometimes when I walk somewhat slowly on the sidewalk and there is only one person behind me, they tend to try to pass me by going faster than me.
Sometimes, I like to mess with them. The art here is to slowly walk faster, so that you walk at the same speed once the person is right next to you.
Then they'll start walking faster than intended, almost running if you do it just right - art is doing it without them knowing you're trying.
Ain't I a stinker?
