No wonder why my big brother and I never fought when we are little. I know I should not believe everything I read but this one I have proven correct. I am a Leo and my big brother is Aries. We value each others opinion and we don't need to speak the exact words and we understand each other.
I can say the same with DH and his father. They are not the best of friends but when they talk they can understand (may not agree on everything) but always meet in the middle with most issues.
HAPPY BIRTHDAY BOTH!!! I WISH YOU ALL THE BEST.
