Hi @zeleiracordero,

I am a little confused. Tell me, did you use the translator and translated from Spanish to English? I'll tell you why I am asking... For example

He said to himself, concentrated on his task, absorbed in himself, oblivious to the explanations of the professor who, for a time, had been explaining.

"Liam, pay attention, listen and then apply."

"Excuse me, Master... Was he talking to me?"

So the professor has been explaining something and Liam was oblivious to his explanations. He was thinking about his own dilemma. Right?

Then Liam is asking someone addressing him "Master". Who is Master? And the question is strange

"Excuse me, Master... Was he talking to me?"

Who is "he"? The professor?

So, there were three people participating in this scene: the professor, the Master, and Liam. Then who is Master?

Maybe what you meant to write was:

"Excuse me, Master... Are you talking to me?"

or

"Excuse me, Master... I didn't know you were talking to me"
