Well, political insecurity, limited freedom, unliked jobs, chronically and above-head indebtedness (just to name a few)... - Funnily enough, a couple weeks ago, I went swimming, and a Thai bloke said to me: "I like how you're smiling." Took me aback at first, but then I thought, well, I'm doing okay, so being contented, I was smiling just because I felt good, and it had nothing to do with other people.
