Relationships between most cousins either tend to be a very close one or quite distant.
I can say with certainty that to me, you are and always have been part of the former.
You are someone who I know I can always rely on for fantastic support and advice. You have always been there for me and I have only great memories of us growing up together.
Thank you for being an integral part of my life, dear cousin.
Wishing you a very happy birthday today and many more joyous birthdays to come!
