Texans are very friendly for the most part; many know no strangers. Texas is laid back but the smaller towns are even more relaxed. Don't be surprised if standing in the grocery store line you get angry because the cashier and their current customer are having a long conversation; you would have thought they were life long family friends...how's your mom, where are the kids, and so on. Texans are very family oriented, family usually comes first over work. I realized this last opinion after moving to Maryland from Texas. We didn't last long up there before moving back home to Texas.
Hope you enjoy your experience if you do decide to move this way. Linda
