FYI i have spent the last 5, almost 6 years of my life living at home with my parents, working part time retail jobs, and then going to live at spiritual ashrams around the world. In different countries. Then go back home and work and then leave again, until i figure out a more long term plan. These communities feel more home than my own. I work retail jobs or nursing home jobs and then leave. The only ashram i have lived at and worked at was in america. Because that's america. Just saying this so you can see a more broad view of things instead of black and whiting things like you are. So i can "self fund" for some time, take time out of the year, and visit one country, and also be poor enough to not apply for an actual visa. The downside of this is that i never had any savings, ever. Due to the nature of saving then spending it on traveling. And when i travel it is never leisurely. I live in ashrams with strict schedules.
But this roundtrip ticket to thailand was a gift, and the person who gifted it to me will also get me a ticket back home too since i decided to stay longer than the original 3 weeks as planned. So i came with very little money because i originally planned 3 weeks. So yes i am "poor enough" to not afford a regular visa. I cannot prove bank statements that have enough for an actual visa. Hence, visa exemption works for me.
My spiritual teacher lives here and he is very old and sick. I figured... while I am here, might as well try to stay longer to be near him and try to help. Because once i leave - i do not know when i will come back.
