as the other guys already warned you, no no no. Don't even ask or try to apply for a visa, it'll be rejected and that might give u issues in the future. Don't do that illegally, the thai businesses around your friend's will call the police within hours
I know that god, it was a folk back in 2005 who used to record all those chicks of soi 6 without using the rubber. He collected all the stds and even discovered a couple of new ones. His buddy used to shot the "asian street meat" series. You can check it out ;)
I came to thailand when I was 19, I got a PhD in mongering with a thesis about the macroeconomy of soi 6. Sick buffalo requires no more than high school, that's the ABC of thailand.
I was in thailand by myself when I was 19 and nobody was wiping my ass. At that time there was little to none internet and most of the time I was on bangla surrounded by walkers. Let him grow and get in sh*t sometimes otherwise he'll never learn. Doing a border run is one of the easiest things in the world, literelly every tourist boot can organize that. I'm not trying to be rude or an d1ck, but let him handle this situation, jeez
I hear many people mentioning about an emergency passport which will be given within a few days but with the validity of a year only. I guess you should do that first, do your border bounce and then apply for a regular passport. just my 2 cents
80% of the thai people living in bangkok lives decently with a budget of
*****
k per month. What makes BKK expensive are the western restaurants, bars and h00kers. Avoid those and you'll easily have a good life with that budget. PS: I just had a month in phuket (which somehow can be more expensive with bkk) and I could live more than comfortably with 100us$/day (I don't drink and I don't meet "girls" when lonely)
