sides to talk over the barbed wire. it's this closeness, these personal ties that mean that many here aren't ready to believe that armed conflict with russia is even possible for us to mature. but usually we hear all the scary things in the news, but i just can't imagine it affecting us here. there's no animosity between us not from a to missouri milligram. that may be the case, but the tanks
