My T and I are in the same social group. Does that count? When we discovered this we worked out boundaries like how we would greet each other, areas to talk about etc. We usually keep it pretty brief and never discuss T at the meetings or the club in T and try to keep our distance as much as possible. Unless there's something pretty exciting happening then one of us might bring it up in T. But its a small country town so you'd expect to run into him down the street but I never have.
