Sure, it might look as though I forgot your birthday, but really you should be impressed by how early I am for wishing you a happy birthday for next year!
Happy 18th birthday from dad, my dear daughter! Watching you grow up and blossom into the beautiful woman that you are today has been my greatest joy in life.
It’s natural for people to want to care for the elderly, so don’t be surprised if they start offering you help when crossing the street! Happy birthday, old lady!
