I have been thinking about the seemingly sad-looking people sitting by their RVs as reported by the OP.
Are they really sad, or just appear so? And if that sadness is real, does it have anything to do with RV? I mean, perhaps these people's flaw is that they expose themselves to passersby, rather than sitting sad inside their stick-built homes. What if they are old and sick? Again, the RV part may be simply incidental, and not really having anything to do with anything.
I have not been around an RV park (though I can't help being soon
to have seen these sad people. But we have often been to hospitals and nursing homes, to see and to take care of our ailing parents. There, I have seen a lot of sad people. Isn't that the fate of all of us?
Is there a way out? Shall I resume smoking, eating whatever I want, in hope of dying of a heart attack, to "die like a man" as it has been said here in this forum? Sounds like a good deal to me, but is it really guaranteed? Or does it simply increase our chance of a debilitating stroke, followed by lingering with a much reduced quality of life?
As one of my friends liked to say, we'll never make it out of this world alive. Perhaps we should not be so harsh...
