You can share this day, but the joy that I feel for you does not need to be shared, because I have enough for each one to feel very loved on this day! Congratulations, cousins!
I have a lot of fun with you and the friendship we have. It's amazing to grow up with cousins who, in addition to being twins, are still wonderful to have around in all situations.
May your day be as nice as it is to have you in my life. Congratulations and best wishes!
