Communication
About 20 years ago I sent this telegram to my parents in Mexico. They had been living in Guadalajara for six years, and were still on a waiting list for a telephone. It took one week for the news of their grandchildrens' birth to reach them. Now we are able to instant message family in Mexico with high speed internet. Cell phones are available, even though they often don't work in the mountainous regions. The communication revolution of the past quarter century has brought a degree of paranoia to some. Personal information is readily available if you want to look for it. On the other hand, it brings a sense of community and connectivity in a different way.
