Seriously, love this girl so much.
For anyone who hasn't read it, check out Story of a Soul, her autobiography. It's a quick, powerful and beautifully simple treatise on the spiritual life, and you will fall in love with her Little Way.
I can't put my finger on it exactly, but my entire family has had a devotion to her from way back when, and we have a fond collective memory of wee Christina (the youngest Senour sister), composing and performing a St. Therese rap for her 5th grade 'Famous Person I'd Like to Meet' project. For realz. And in public school.
If you do nothing else today, toss a quick prayer Heavenwards for her intercession. And watch out for roses! (I was surprised with a dozen of the red varietal last night by a very thoughtful husband, who claimed ignorance of knowledge of the dawning of October.)
