I'm not quite exactly sure how to take this, now that I think about it. Like all brilliant poetry, there are many facets to explore and angles from which to view it. Be that as it may, my son, Paul, age 23, has a Shakespeare class at university and decided to dedicate this to the senior people in his life. The dedication was instigated when he said that no one told him they grow up so fast, referring to his five-month-old daughter. He got a shower of 'cry me a river' from his middle-aged relations, and so thus came the sonnet in reply. I am going to go with my knee-jerk response on this one and proclaim it a beautiful sentiment and an undeniable truth.
