I've missed a ton of comments because ... I had real life to tend to, so maybe this have been said. The fact that the boy drown, and was pretty close to shore ... I don't know, it makes me feel worse. I believe the dad did everything he could to save his son, do NOT get me wrong, but I think if I were in his shoes I wouldn't be able to shut the part of my brain down that was telling me, "why didn't you stay in the water looking, the gator dropped him and you could have saved him," etc.
Again, I 100% believe that the dad fought with every ounce of fight he had, but it's "normal" to have those hind-sight doubts.
Those parents and the siblings are so on my mind and heart.
