I drafted a little letter for you guys, just in case of any necessity.
My cousin Cesar is the Secretary of the Interior. My cousin Lupe is the Attorney General -- lots of others at various levels of government, too. My grandad was VP in the 50's and his grandad was one of the original five founders of the country. I have to look in my papers, but I believe I have some sort of silly honorary title of some sort.
Print this out, fill in the blanks -- name and country of residence -- and show it to anyone who give you shit. But, there should be nothing to worry about, just use common sense --
