Dear tiffy,
Here's a heartfelt Happy 18th birthday kiddo!
Many happy returns.
Though you make my blood pressure rise at times, you can be quite unbearably adorable too.
So enjoy your youth, while you can.
You're the only one who still gets away with everything.
Stay round & happy:)
Cheerio,
your equally annoying sister
Dreaming of a new day ahead!;
Just making my way through the crowd
