Excellent. This piece has a lot of potential. I like the elegance found in the language while illustrating to the reader how precious time is. It has a timeless appeal to it. I also enjoyed the word choice for the acrostic. A grammar course and an excellent poem. Inspirational for writers.
An excellent assessment of the saying is the glass half full or half empty. This saying seems to be a lighthearted exercise use to determine how one thinks. I always feel I never have enough information on the glass. Is it water when I thirst? Is it poison? Are we so into consumption that we must always have a full glass? What if the glass is a metaphor for a window or a room? An interesting conversation piece.
