finally our last rung

Next time someone tries to cut me off,tires will be smoking on the pavement as I squeal past them into my spot.And finally our last rung: we take action.We back up, pull up behind his car,honk our horn, and roll down our window to scream a few choice words as well.Now imagine,he walks over quickly, apologizing.His wife, who's almost due with their first baby,called him from inside the mall to say she is in labor and needs to get to the hospital immediately.We're momentarily shocked,apologize profusely,and wish him luck as he rushes toward the entrance.
