You go into the candy store, and grab a few piece of candy, then, as you count your candy, you accidentally bump into someone at the counter. It's Skid! You help him, apologizing. "It's fine, don't worry about it!" He says, the kid then walks away with his candy and waves goodbye to you and the guy at the counter. You pay for your own candy and walk outside, where Skid seemed to have been waiting for you. "Hi again!" He says. Do you say something back?
