You’re walking toward the seventh green when you notice the mud packed into the face of your wedge.

You reach for your towel.

Nothing.

Maybe it’s still hanging on the cart. Maybe it fell off somewhere around the sixth tee. Maybe you left it beside the last green after cleaning your putter.

It isn’t exactly a golf emergency. But that’s the point.

A round is full of tiny interruptions like this: looking for a towel, digging around for a ball marker, hunting for a divot tool or trying to remember which pocket swallowed your tees. None of them ruins a round by itself. Together, though, they create friction.
