Of course, Ryan wouldn't be able to tell her the real reason why he was coming back home somehow late.
Telling her the real reason would be super stupid...it would just be like making use of his hands to put him and Sofia into serious trouble.
He would have to lie to his mum right now, and that's exactly what he did...
"We were handling a certain project in my classroom which had been given to them before I resumed school. But since I was a student in the classroom already, I had to participate in the project". Ryan responded to his mum's question.
Emily nodded her head a little before saying, "Hmm, so this is the reason why you're coming home just now".
"Yes, that is the reason mum". Ryan stated.
He wanted to add another lie to back up the one he'd just told, but he decided to leave it at that...the one he told was enough.
