Teen pregnancy

I took the lesson with teacher L today; it was the first time this year.
Since she was so talkative, our topics were fast-paced, like a merry-go-round.

I don't remember clearly, but our first topic was schools shut down.
The teacher told me that she had heard the news about Japan; many schools were closed.
I didn't know about the matter, but I explained to her it happens ordinarily, especially in winter due to the flu.

It depends on the school; the principal decides how many students have caught the virus and whether the school or class will be closed.
During the shutdown, even the students who haven't infected also needed to stay home.

And then, she burst into laughter.
She told me that her other student had been to Tokyo Disney Land during the school shutdown.
Naughty girls!
I'm sure they thought they had an extra holiday.

I don't remember how the topic changed, but she told me many teenagers were pregnant in the Philippines and were cold about "teen pregnancy."
I had yet to hear this word.
Almost all of her neighbor teenagers already have children.
I am like a grandma to their babies.

It was uncomfortable to speak during the class when I tried to talk, and I felt something wrong in my mouth.
I can't explain it well, but like overflowing with drool, I remember I also thought during the last lesson.
I had an experience like that before, but I don't know how I recovered.
What can I do?
