Bart has tried texting Sonic and Sonic would be glad to see him, but Sonic in this case is the one who hasn't responded. He doesn't like to text and says he doesn't know what to say. With Bart in St. Louis and unwilling to drive to Chicago, they havent seen one another for years. Sonic does t drive and, being autistic, prefers to sleep in his own bed, not travel. He would not like the train and cant afford to fly there.
