I've traveled to Mexico.  It is known as the United Mexican States. 
I love Mexico! What is your favorite part?
I like the part that closely borders the USA the most. 
I have only been to the capital city - but would love to see more! How about you?
Yes I like visiting Mexico all the time. It is the sixth largest country in the Americas so there is plenty to see. 
Wow - I did not realize that. Do you like the food there?
Yes I enjoy Mexico's food.  It is probably my most favorite food to eat.
