As we walked to school on that first day, my mother (with my sister in the pushchair) and I, she said "If you want to go to the toilet say, 'excuse me' to the teacher."
Of course, with the strangeness of it all, I forgot what it was I was supposed to say. Naturally, I needed to go to the toilet and I remember wondering what I should do. In the end I just left the classroom without saying a word, all the time afraid that the teacher was going to call me back, come after me, smack me, I don't know.
Just in case you're thinking that I could have used some other words, I could not, because I didn't know any words, not English words, anyway. The only foreign child in the class and quite unable to exchange a word with anyone.
After I had been at the school a week, my mother asked, "Do you understand anything the teacher is saying yet?"
"Yes, everything," I replied.
"So, what did the teacher say today?"
"Oh, nothing interesting. Exactly the same as yesterday."
