The Feast of St. Rita of Cascia
is today. There is information on her here.

I actually have a St. Rita story- years ago, my mother was driving around in a mall parking lot on the day after Thanksgiving. (Don't ask.) I was in the passenger seat, getting more and more frustrated as time went on. After about half an hour of driving up and down completely filled rows, I thought of St. Rita's patronage of those with impossible causes, and cried out, 'St. Rita of Cascia, intercede for us !'

The second after the words had left my lips, someone pulled out of his parking space- immediately in front of us, so that we could pull in very easily.

I know, it's not exactly a big deal, but it impressed me at the time....
