Shen Yuan nods. "If you want to go back to your book, I don't mind," he offers. "No need to force conversation, I just thought it was time I introduced myself." He's not entirely sure how to say and reassure you that at least one of your son's friends doesn't hate you without reminding Lancelot that multiple of his sons friends hate him, so he doesn't. The politeness will hopefully serve that purpose for him.
