Friends come and friends go, but a true friend sticks by you like family.
~ Proverbs 18:24 The Message
Even as a child, I learned one particular non-negotiable relationship issue. It was trust. I learned that the difference between someone my grandparents were friendly with and someone for whom they counted on was predicated on trust. My grandmother was wicked smart; she watched people; she let people have the time it took to teach her whether or not she could trust them. I’m not sure if others necessarily knew which list they were on, but my grandmother was crystal clear. She could be friendly with everyone, but she trusted only those that taught her they could be trusted. She was patient; she waited for people to teach her who they were and if they could be trusted with her most vulnerable realities. For her, trust was NOT about total agreement on all subjects, it was about whether or not a person had the capacity to care and be cared for as circumstances dictated.
My grandmother maintained a certain amount of watchful but kind distance in some relationships, she even had a couple of notable compassionate endings to relationships that proved incompatible with the community she was part of. Many benefited from her quiet ability to be a good friend to others and choose her own friends wisely.
