During pregnancy my dear wife suffered from some pretty weird dietary cravings, chocolate & pickle sandwiches and fish sticks with ice cream becoming standard if stomach-churning fare for a while. One day she declared that she just HAD to have 'some of those nuts that you get on those chocolate whirly things.' I stifled a laugh and asked what kind of nuts these might be.
'You know, those nuts that are on top of Walnut Whips.'
Cruel of me, I know, but I held out for three days while she grew increasingly irate, before suggesting the word 'walnut'. She still blushes at the memory.               

Same wife, same pregnancy; Approaching both confinement and the dimensions of a barrage balloon simultaneously, she could find no clothing loose enough to cover all three of her. Arriving home from work one evening I was greeted by her showing off 'her' new comfortable attire, MY sports trousers, and asking 'What do you think?' It was one of those too-few sublime moments, and I just smiled indulgently and replied, 'Well, darling, you've always wanted to wear them.'   

Same wife(amazingly), some years later, her birthday; Early morning, the kids have left for school, and she staggers into the kitchen and sits down at the table. 'Oh, God, I'm forty years old. Forty years old, I can't believe it?' She looks across at me and asks, pleadingly, 'Do I LOOK forty?'
Me, ever the gentleman: 'Naw,' then, after a short pause, 'You USED to!'   

PS Mr & Mrs Ythanside are still happily married I know, I know, I can't quite believe it myself.
