“I’m currently not a Texan, but grew up there.”
Never heard anyone call themselves an ex-Texan before. Wow.
Kinda like going overseas and someone asking where you are from. If you say the US, USA, or something similar you may get an inquisitive look. But say Texas and they'll nod in the affirmative and maybe even smile.
We've got a freeper by that moniker. Informative poster, at that.
I consider myself a Texan, but there are quite a few in my family that don’t consider me one, especially since I married a Californian and have lived in California for many years.
