I have never actually participated in the activity that requires you to trust others to catch you if you were to fall backwards, yet this image is very much based on that concept.  Trust is the hardest thing to gain and the easiest thing to lose, and is so important for our relationships.  Trust between spouses, between friends, between parent and child.  Love this quote “Whether it’s friendship or relationship, all bonds are built on trust.  Without it, you have nothing”.
