Well they aren't related to Singapore specifically, more or less Asian culture as being more conservative than American culture. It can be really hard to meet locals here, as many stick to themselves and find talking to a stranger somewhat weird, much less making friends for no reason. This can be seen especially at clubs, where you go and hang with your group of friends rather than meeting new people. I was just in HK for a week and really liked it, it seems more vibrant than Singapore as far as the energy of the city.

Many limits I ran into were personal including health conditions and it turns out humidity really makes me sweat which I never realized. Also in India for some reason eating with my hands made me so uncomfortable, whereas eating with chopsticks was fine and I learned it quickly. The language barrier wasn't too bad since Singapore is English speaking, although the accent can be really difficult sometimes so speaking slowly is sometimes needed. I knew Asian culture was more conservative as I've been to South Korea before and have a lot of friends there from research at my home university, but I really thought I could make local friends anywhere despite a quieter culture and that turned out not to be the case.
