sky scrapers

Sometimes I wonder if Mexicans aren't a tad paranoid in the security department...YES, I know that I live in a dangerous city, but some precautions seem a little over the top.  Having a balcony and never wandering out to take the sun??  Barring all of the windows, even when you live on the third or fourth floor??  The following is one of the more common security measures taken by Hispanics, even in the U.S.  I, for one, like to inspect the colors of the glass chosen to protect the houses that line the street corners and maybe, if you're lucky, the sun will strike just right, creating a lovely rainbow...
