SPOILER ALERT -- Mom was about to be an empty nester:
Mom: You know what I'm realising? My life is just going to go. Like that. This series of milestones. Getting married. Having kids. Getting divorced. The time that we thought you were dyslexic. When I taught you how to ride a bike. Getting divorced... again. Getting my masters degree. Finally getting the job I wanted. Sending Samantha off to college. Sending you off to college. You know what's next? Huh? It's my fucking funeral! Just go, and leave my picture!
