This document discusses the changes that can occur in a marriage over time. It contrasts the feelings of newly married couples after 7 days of being married with couples married for 7 months and 7 years. For newly married couples, there is an expression of love, but after 7 months small disagreements emerge and spouses question each other's purchases or activities.
