I included this picture because of the children seen in it.The children wearing starched white shirts are working in the supermarket checkout,some as young as 6 years old.Because Mexico is so impoverished,the children only attend school in most cases for 1/2 day.The other half day they work if they can find employment such as a supermarket.After they finish a long day of work they must still do their homework.They were such wonderfully polite kids.
