For the sake of my son Gideon (age 12), I strain my brain each week to make this column something zany and irreverent instead of soberly persuasive.I beg his indulgence this week, as I celebrate 25 years of marriage to his mother.I’m halfway through writing a lighthearted-but-practical book about marriage (“like” my Facebook fan page Tyree’s Tyrades if you wish to receive updates), but I’d like to use this week’s space to share some highlights.With all due respect to Johnny and June, marriage deserves a stronger beginning than “we got married in a fever hotter than a pepper sprout.” Your significant other should be much more than an object of lust or infatuation.
