Dear
Lucy，
Next
Monday
is
my
20th
birthday.
Imagine,
there
are
already
twenty
years
behind
me!
No
wonder
I
feel
old!
My
parents
are
giving
a
dinner
party
to
mark
the
party.
The
first
person
they
wish
to
invite
is
you,
my
childhood
pal.
Indeed,
all
of
those
20
years
are
more
or
less
associated
with
you.
We'll
be
expecting
you
any
time
after
six.
See
you
then.
Yours，
XXX
