Another year older and wiser, or I suppose
just older in your case!

Don’t worry, though! You still have many
years to come where you can learn from
me and gain some of my wisdom!
We must be related because you have so
much style and sophistication just like me!

If people didn’t know any better or that
we’re cousins, they would definitely think
that we’re sisters!

Happy birthday, my dear! I hope you enjoy
your special day today!
