Don’t cling. Show commitment.????
Well, let’s try this for an analogous concept.
Clinging is likened to a weed that grows and grows, choking all the other life out of existence.
Commitment, of love, would be like a Rose. Inviting and beautiful, with limits. Hence the thorns.
Unless, of course, you just smoke it, and IT only chokes YOU.
Those are seriously good analogies. They cover every point necessary to understand both concepts completely and their difference in two sentences.
