Memories

Going through old photos I found pictures of tiny Sydney. Let me be the first to say the cliche, "Where has the time gone?!?" Found some pictures of the time before our worlds got rocked with the emotional equivalent of an earthquake with a tornado. Can someone tell me why these photos make me feel such a cognitive dissonance? Could it be my brain has blocked out the memory of hurt for so long I just don't know what to feel? Neurotransmitters are definitely confused.
