We further established that we had been on opposite sides of the US/Vietnam conflict and had more than likely been firing our weapons at each other during the Tet Offensive in January of 1968.
We both had too many details of the battle near Tan Son Nhut Air Base for it to be any form of coincidence.

When we arrived at Houston, he bought me a meal and we became friends. We are still in touch today.
