Dad:

"My younger brother married for a slightly more positive reason ...they were best friends.  But that friendship was based on common interests, mostly fun things they enjoyed doing together with other friends.  But when he lost his job, the fun was put on hold, and things began to disintegrate during those difficult times.  And the struggle just intensified ...with each focusing on what bothered them, instead of on past fun times.  There was not enough depth and strength to endure a friendship that had not seen anything but easy living."
