Graffiti Artists (The Good Kind) Strike Moraga's SiSi Caffe

Moraga business owner Cathy Corsi found a nice "good morning" message on her doorstep when she arrived to open and her adjoining hair salon Saturday.

This local "graffiti vandal" expressed his or her sentiments in a nondestructive way, leaving a message for Cathy in a biodegradable, water soluble medium instead of the usual spray paint or magic marker.

"I love that the kid did this in chalk," Cathy said. "And they expressed how they feel about us. I thought that it was very sweet."

Yep. We agree.
