Marriage is an educational institution, one where graduation is impossible and dropping out or expulsion is the only escape. I should know; I flunked out on my first attempt, but it wasn't my fault. My primary instructor was distracted tutoring other students. Now I'm enrolled in another institution of higher learning, the School Of Kellie, and while there's still no hope of receiving a diploma, there's little risk that my tutelage will be interrupted because Kellie's campus is closed to new admissions. She has all she can handle with her one transfer student who is on perpetual academic probation. Thanks to my sustained lackluster performance, frequent remediation is required, and I regularly get schooled. This week's lesson, conducted aboard the Celebrity Century while cruising along the California Coast, explored the limitations of inductive inference in marital relations.
