Love that well which . . .

For future reference I want to make just a quick note here on Sonnet 73, by William Shakespeare.   

This poem contains one of my best-loved lines of poetry -- "Bare ruin'd choirs, where late the sweet birds sang"   

Only this afternoon, however, did I become aware of the rhythmic, wise, last line, "[ ] Love that well which thou must leave ere long."  Wonderful!
