Riley & Lucas
Lucas shook his head. "I told him not to tell me! There's no way I'll be able to keep it a secret from my mom. She's like impossible to hide anything from!" Not that Lucas ever tried to hide anything, but he was definitely discouraged from doing it just because he knew his mom. His dad wasn't exactly easy to hide things from either.
"But I'll tell you when we go ring shopping!" That would be easy. "And I'll show you a picture of which one we end up picking." He knew she'd appreciate that.
