- The language is not mutually intelligible with Russian in practice, try to learn it;
- But in case you're already familiar with some BCMS/"Serbo-Croatian", keep in mind Bosnian standard is based on the Ijekavian variant (Proto-Slavic *ě > je/ije, *x is retained as h, still pronounced [x], and there's sometimes prothetic h where there shouldn't be, like hrđa 'rust');
- Islam is not very impactful in daily life, it's a secular society not really different from the rest in the region;
- Also yes, I second Slovbro, in my experience they are much less holeric and rude in temperament than S*rbs on average;
- Don't do kacap things in public (no liberating toilet dishes, denazifying washing mashines, sitting on bottles or asking "where's the гречка" in the supermarket) joge was self-made'd :DD
P. S. Damn formatting, oh well.
