The cast of Teen Titans Go! signed: Pete Michail, Aaron Horvath, Tara Strong, GregCipes, Khary Payton, and Scott Menville were all very nice. Tara Strong apologized for being distracted as she was Facetiming with her child. It was nice that she was trying to stay connected to her child. It was nice of her to apologize. Greg Cipes gave me some dog tags promoting an animal kindness group.
