Latin Americans (Colombians, Venezuelans, Mexicans, Brazilians) and Southeastern Asians (Thai, Filipinos) are super warm, friendly, and expressive to me.  Particularly those from the country side / small towns (pueblitos)

That is one of the most important reasons why I am learning Spanish and Portuguese.  In my opinion, if you are going to learn a language, it should be one where people from that country / culture are welcoming and appreciative of your efforts to learn that language.  Latinos have never gotten made fun of my American accent or incorrect grammar; they were always so patient with teaching me and appreciating my efforts to learn their languages.  It motivates me to keep learning, which creates a positive feedback loop :)
