Would you share a straw with a stranger?
In my country, Argentina, we have the Mate, our national drink. In which you share a straw to drink the tea. It is an amazing feeling of community but in the US people find the idea repulsive. Here people put the names in the children cups at birthdays (the best part of the birthday is to drink from your friend's cups, remember?) Who would you share a straw with? Family? Friends? How about a strange?
