No Greater Love

I just recently came across this audio slide show on The Washington Post's website that left me with a lump in my throat and tears in my eyes. The Post's simple introduction tells you all you need to know:

Classie Morant, 104, swore that as long as she had strength, she would care for her bedridden sister, Rozzie Laney, 92. For more than 20 years, she has kept that promise.

(Don't worry if the slideshow takes a minute or two to download -- it's worth it.)
