To my best gal back home, Happy Birthday! If you were here, I'd make you this. But since you're not, I'll send you this. You're the bestest friend, because we can live forever apart and see each other once every 12 months and it's like nothing's ever changed.
Hope your day is extra special--have a drink (or two or several) for me, and I'll for you. I'll (imaginary) toast to you and our future adventures together.
