Today, Oscar-winning actress and all-round likeable lady Sandra Bullock gave a surprise commencement speech at Warren Easton Charter High School in New Orleans. Bullock — who donated to the school after it was damaged by Hurricane Katrina — had plenty of wisdom to impart, from sweeping life lessons about finding what makes you happy and not being afraid of the unknown, to practical advice on avoiding one-armed hugs and not picking your nose in public. It was very sweet.
