Give and take. Isn’t that what life is about? It’s like you can’t be in two literal places at one time. Or even in two life stages at the same time. Giving and taking infers sharing, trade-offs and compromise which occur in interactions between us and others, or within ourselves. Very good things in themselves.
But contrast, aah, that is where the juicy, messy stuff is. According to the dictionary, the verb contrast is “to place in opposition to set off differences”. Contrast is where I find a world of nuance and subtlety, differences coming together into a new forms, brainstorming producing possibilities that participants never imagined, the third way of being which results in true choice. Contrast heightens the beauty of separate objects. Contrast makes space for humankind to shine gloriously in the uniqueness of each of us. Contrast has a shadow side. Sometimes contrast makes people see the worst in each other when they are blinded by hanging on to forms of differences that can divide.
