Nothing as endearing as seeing a Dad on the train doing the final morning preparations to ready his son for school. Hair brushed and flattened. Collar sorted and tie yanked down. Jacket straightened. Lip balm applied to the smallie’s chapped lips with all the panache of roller painting a wall so the small fella now has an inch wide grease track the whole way around his mouth. And the look of sheer adoration as he gives his dad thumbs up would melt even the coldest of hearts.
