Oh dear Lord. It took me 3 hours to figure out the name of this book. I kept Googling... pink book, 80s, girl sitting at typewriter and NOTHING. Finally I started looking up Tessa? No... then it occurred to me... I, Treeny? No. I, TRISSY. EFFING A I FOUND IT.
All of that to say that I read this book a lot as a kid for some reason but had no memories of the plot except she would type curse words on her typewriter. And of course, I remembered the cover.
Ok, now I can go about my day doing other things.
