Where's Grandma?

My friend Julio related an amusing true tale once.
He lives in Guadalajara, and if you've ever been there, chaos reigns in some parts (though the Minerva Fountain area is quite nice). Like many traditional Mexican families, his mom, grandma, and sisters have lived together for ages. Julio himself lived with them until he married, and now lives blissfully I'm sure without all the riff-raff hanging about breathing down his neck, and that of Viviana.
Anyhoo, one day, his grandmother wasn't at home anymore. One of the sisters saw her leave the house to go on an errand, and, well, she just never returned. For a week (A WEEK!) the entire family combed the dusty streets of Guadalajara - which is Mexico's second largest city - to no avail. Of course, you can imagine the thoughts running through their heads. Is grandma in a ditch somewhere? Did she get kidnapped and sold in Tijuana to a guy that specializes in geriatric donkey shows? Is she hungry? Speaking of hungry, whos going to make the posole now?
Finally they found her. She had grown tired of living with them and had checked herself into a retirement home without mentioning it to anyone. Now that's a woman who knows how to get things done!
