The ties that bind...
... are sometimes the shared experiences that involve being on opposing sides of a damaging conflict.
Imagine war veterans from opposing sides gathering for a fellowship supper. Both sides have suffered bitter losses at the hands of the other, yet in all those painful memories, a common bond exists.
In fact, such gathering can go a long way to healing wounds... stop the bleeding, so to speak. Like the opposing Taurus symbol "A Red Cross nurse", in fellowship one enters a 'zone' free of violence where healing and care may emerge without fear of attack.
