We likely all know the trope of whether a half-filled glass of water is half full or half empty. In truth, the glass is completely full: half water and half air. Both are vital to our survival.
Like the cycles of the moon, our lives are said to wax and wane. Coming into my seventh decade, I am by force of nature inarguably waning, and yet my life is full to overflowing. As the cycle continues, I am quite curious as to where I will find myself at my own next new moon.
whole moon half-hidden
wax and wane like hide and seek
steadfast in the sky
What Rhymes with Stanza? 
Or, from an engineering perspective, the glass is twice as big as it needs to be. 😀
