I just returned from a lovely tour of Eastern Europe. My only disappointment was the stingy and self-absorbed behavior of my fellow tour travelers.
We saw much poverty. Ragged and probably homeless people were selling many small items to make a little money to survive.
For example, one elderly crippled woman was selling T-shirts for $5. Our tour guide reminded us that we should bargain with her and try to get the item for $4. Of course, many people in our group did this with great passion.
