He is a new teacher at our school.
He arrived last Spetember.
He is tall and strong with a square face and he mostly wears black.
He's always on his own and he isn't very friendly.
One day, we saw him on a dinghy, going towards a huge yacht.
And yesterday, at a Assembly, a piece of paper fell out of his pocket.
it read :" Lane Technology School Chicago. Black June 30th"
Did he do anything wrong?
Was he a teacher at your school last year?
Thank you for your help.
Oliver, Shanti and Alwena
