I never realized I had someone who shared the same birthday as my immediate younger brother and that is my very good friend 
It's been five years and counting since we came in contact and you've been indeed a friend even though you've got flaws that most times make me feel like bashing your head on the wall but I guess everyone has got flaws too, so I am willing to bypass that for the sake of today.
I am glad to see you be among those who are opportune to see today and to count it a day of their birth celebration. So, this is me wishing you a wonderful new phase of your life with an abundance of God's love, God's mercies, God's blessings, God's favour, God's healing
I am indeed grateful that you are part of my bloodline, although we've had our ups and down as siblings but I am always glad we are siblings.
I am proud to be called your sister, and I pray that as you enter unto your new phase of life, may God bless and enlarge your coast, may his countenance shine upon you, and may He bless the works of your hands.
I wish you both the best of life and may your light so shine that the world will see it, you both will not die but live to declare the works of God in your life.
I know difficult times will come but there will be strength, wisdom, and grace to scale through.
