I have been to Brazil and Argentina twice as well as Chile and Paraguay once and one thing I find delightful the warmth of the people from all over. I have been to 30 countries (most in Europe and a few in Asia) where people are more stoic.

Being from the USA we smile a ton (even if it’s fake). I noticed this mostly in Brazil as well as moderately in Argentina but less in Chile. Paraguay I can’t say much because it was just me seeing customs guys and leaving the country to get a picture.

Remember a Brazilian guy telling me when it was me and two French guys I look more “French” because of my facial expressions. I have what is called a resting bitch face and I am a direct person so this could be the case.

I think if you look at all the Americas (Canada to Argentina) you will find we smile more than the old world maybe due to an immigration thing long ago? I am not sure but it feels nice that I don’t need to feel insecure and I can smile at someone in a store and think I work there like I did in London.
