my lock dwon

Sir uses a mega phone to say this is a lock down he goes on and on we had to walk sensibly to the rooms. The year 4 and 5's went into the teachers room. he year 2 and 3's went into the break out room until sir said  it is  all  clear to come out . We had to sit and be quiet with our backs  to the wall and wait until it was safe to come out.
