God bless my mom. Despite (and because of) my semi-severe Oprah aversion, she emails me links to worthwhile stories from the show. This was one that I came across while viewing another story:
Faith the Dog
If you want to see the segment from the Oprah show (it's a tear jerker), go to oprah.com, click "videos," and look for "Faith the Dog" after you are forced to watch the Best Buy commercial (boo, web commercials).
My kids have both had some questions recently about why this person talks funny and this person can't walk, etc. The Faith the Dog video created an opportunity to talk about differences, and preseverence.
