During all this I heard the door open. You can't actually see the door from the classroom but it's all the same room. When my boss comes into the school he always calls out to let me know it's him and not a visitor, parent, random salesman etc.. Most of the time he calls out 'It's me.' But sometimes he will call out something to do with what I'm teaching. 'Can you see something green?' or 'Does it start with A?' or whatever. So when I heard the door open and I called out 'hello?' and the answer was 'trick or treat' I replied in kind and continued teaching. After about 15 seconds there was another call 'trick or treat?' That seemed a little odd... A couple of the kids were interested, too and peeked around the divider to see the door. Big wide eyed faces turned to me 'It's not R-sensei!' 'Hmm? Is it K-sensei (R's wife)? It didn't sound like a woman's voice but maybe she has a cold...?
Even wider eyes- 'Nooooo!'
I picked my way carefully between all the kids and their bingo cards and made it to the door to see a calm but slightly impatient looking man in a uniform.
Holding a package.
He looked relieved to see me and repeated:
Not trick or treat, takkyuubin! (courier)
I apologised, signed for the delivery and tried to explain the mistake but I don't think Japanese men of a certain age really get Halloween...
And I think I have done a bit too much of it this week to make that mistake!
