Lyrics:

Deliver de letter de sooner de better

The upside down stamp meant the kisses were wetter

I.s.y.i.m.d., ill see you in my dreams, honey

T.s., t.s., t.s.a., s.w.a.k.

Xs and os who knows what all of that means?

P.p.d.s.p.e.m.r.m.f.o.b.t. must have took

Lots of hours for you to see

What I was saying back then when we were still green

P.m.p.m.d.s.o.f.'s not hard at all

Please mr. post man don't stumble or fall

I still remember what m.b.d.d.f.c. means

S.d.f.s.d. was a twister

Sprinkled with powder and perfume, my sister took

Two days to figure out sweet dreams forever sweet dreams

S.d.f.s.d. had her seeing double

The envelope looked like a good chinese puzzle

Yes I got those letters you wrote me when we were fifteen.
