You're right. People will do whatever they want to. They can blame it on any number of excuses why they can't or won't do something, but when it comes down to it, you said it best.

They will do whatever they want to do.
Even if they realize it or not.
Actions speak louder than words and I'm sure mine speak volumes.

...Although some have an addendum that I'd love to elaborate on sometime.

But alas it is what it is, and nothing more.
Separate paths lie ahead and only fate knows if they join or not.
Regardless of the outcome, I've got scars and stories to share with the travelers traversing the trail with me.
