Why he died?

Dragon, age 3 years 1 month, in her bed looking up at A's photo on the wall:


Dragon, "Where's A?"

Me, "He's right there, on the wall where he always is."

Dragon, brow furrows, pondering

Dragon, "He died?"

Me, "Yes, Love. He died."

Dragon, "He passed away?"

Me, "Yes, he passed away."

Dragon, "Why he died?"

Me, "We don't know. He was just a little baby when he died."
