Cultural diversity

I was an MBA student in the USA and I lived in the university’s coed dormitory. In my culture, usually, if a woman talks to a man, it is a sign of romantic interest. Therefore, in the first few days of school, I found it strange that so many women were talking to me and I was under the impression that some women on my dormitory floor were interested in me. To return , their politeness, I would buy them flowers or offer small gifts, as is done in my country. However, I was quite surprised to see that these same women now seemed uncomfortable around me. One was even quite offended and told me to leave her alone. Eventually I talked to the residence adviser on my floor to see what I was doing wrong, and he explained to me the way men and women usually interact in the USA. I was quite relieved to hear that nothing was Wrong with me, but rather with the way I was interpreting my conversations with women. Even though I did not find the love of my life while I was in the USA, I still made many good female friends afterwards with whom still maintain contact
