Dear Sabi,
I hope you're well!
In just twelve hours, you'll be celebrating another year of life, and I thought I'd take a moment to wish you a very happy birthday in advance.
Despite all the distance between us, you've always been a remarkable friend, and I couldn’t be more grateful to have you by my side. Wishing you many extremely happy returns of the day, a year filled with immaculate joy, and success ahead.
