Kearney and his wife, a middle-aged couple, went for a stroll in Phoenix Park, Dublin, last week.
They sat down on a bench to rest. It was then they overheard voices coming from a secluded spot. Immediately Mrs Kearney realized that a young man was about to propose to his beloved.
Not wishing to eavesdrop at such an intimate moment, she nudged her husband and whispered, 'Whistle and let that young couple know that someone can hear them.'
Kearney replied, 'Whistle? Why should I whistle? Nobody whistled to warn me.'
