Dear Random Man Who Believes Secession is the Solution,
I frequently run past your truck while you are working in my neighborhood and your "Secede" bumper sticker gets me riled up every time I see it.
I just want you to know that Texas will run out of oil, and therefore its primary means of supporting itself, long before the rest of us will exhaust our ability to govern ourselves peacefully without you.
I guess your expenses will remain low, since your government only convenes briefly once every two years and doesn't believe in raising taxes to maintain infrastructure. Unfortunately though, your crumbling sidewalks will disintegrate completely, your aging highways will cease to allow the passage of vehicles from far-away ranches to urban workplaces, and your citizens who lack healthcare and education will gradually bankrupt the rest of your citizens who do not see the link between themselves and those who go regularly without. However, I am sure you will resolve all of that whenever your leaders finally reconvene in a couple years.
Maybe the nation of Texas will have enough water, but I guess if you don't you will figure something out. I'm sure you won't need any help recovering from any drought, hurricane or fire issues like you have in the past, or any financial aid like the $44 billion dollars you received from the United States federal government in 2010.
Anyway, it sounds like you have thought long and hard about this, and we wish you the best.
Warm regards, and we will see you at the U.N.,
The Rest of the States
