While my brother-in-law Darragh took off for a honeymoon with his new wife Emilie, we joined my in-laws in taking the happy couple’s two-year-old daughter Lucy to Wexford. Lucy is delightful, and our own two-year-old adores her, in that way that toddlers adore and resent all their best friends with equal ferocity. They spent the first two days of our trip fighting over their favoured objects, laughing constantly as they ran between rooms, and generally cavorting like naughty spaniels. It was all quite idyllic, until I developed a severe lurgy on Day 3.
