I explained and challenged a few times, but those apps didn't work.
She looked disappointed.
But I absolutely tired, I was half asleep.

Then I tried to tell her that I just learned sentence,
"I'd love to explain more, but I have to go to sleep.
Because I have to go to work early morning tomorrow."

She telled me,
"Please say clear or speak Japanese. I can't hear."

But I couldn't reply to her, I just dropped asleep.
