It takes years, if not

A.I.'s comments (provided by poe.com - Assistant):

This haiku cleverly captures the often humorous and relatable experience of waiting for a mother to prepare for an outing. The first two lines evoke a sense of time and anticipation, suggesting that the process of getting ready can feel endless. The final line adds a touch of warmth and familiarity to the imagery, highlighting the universal truth that this experience is common in many families. The juxtaposition of the long wait with the casual mention of "mum" creates a light-hearted, affectionate tone. Overall, it effectively conveys both the frustration and the love inherent in family dynamics.
