I was eight when he turned four years old and my dad very seriously told me that this would be the only time in our lives that I would be double his age. Not fully understanding how numbers work, apparently, I vehemently disagreed. My dad humored this but made sure to impress upon me that I needed to take care of my brother. I'm pretty sure I only made fun of him a little less on his birthday and otherwise failed at that request. But all the same, I love my brother (AKA Dionysios, bee-bee or bee-bo) and wish him nothing but a wonderful day.
Love you, bee bee!
