happened.
The
room
started
to
shake
and
before
we
knew
what
was
happening,
Father
shouted
to
everyone
to
get
under
the
kitchen
table.
We
all
sat
on
the
floor
under
the
table
and
waited.
When
the
ground
stopped
shaking,
we
got
up
and
we
weren’t
hurt.
We
couldn’t
get
out
of
the
room,
because
the
door
wouldn’t
open.
My
father
called
for
help
on
his
mobile

and
in
three
hours,
people
came
to
help
us.
They
opened
the
door.
We

up
and
left
our
flat.
