I wasn’t sure how to wish you a belated happy birthday, but I thought it would probably be best to start off by apologising for missing the actual day!
Sorry for the late wishes, I hope you can forgive me! Happy belated birthday!
Seeing how today is your special day, I’m sending my very best wishes your way. I hope you achieve everything you have been working so hard towards and more, as you truly deserve success.
You might be my mother’s sister but to me, you will always be like a second mother. I’m forever blessed for having such a spectacular aunt like you in my life.
