This touched my heart. I was the older sibling, always protecting my little brother. He grew up big and strong and there came times when he protected me too. They must love each other very much. What a blessing.
Thank you for your kind words! Yes, I'm sure they love each other a lot even though it might not always seem so - they're always teasing each other and arguing, very often just for fun. I'm the big sister of both of them, so I believe I know how you feel. Photos like this warm my heart, too.
