People need love. Life without tenderness and without love is just a mechanism for dry grinding and heartbreaking.
A deep sense of love and belonging is an irreducible need of people. We are biologically, cognitively, physically, and spiritually wired to love, to be loved, and to belong. When those needs are not met, we don't function as we were meant to. We break. We fall apart. We numb. We ache. We hurt others. We get sick.
