I have this memory of the first time I seen a ladies breasts. It was a lady from church who was breastfeeding at our house (it was hippy-ish Vineyard church, there was no hiding it under a blanket). I was somewhere between 3 and 4, so I wasn't
that young. But it was a very personal experience, obviously.
What's interesting, to me, is how the memory changed over the years. The colors, and ..um.. shapes have distorted, enlarged, and some details have disappeared completely. It's changed so much that it's probably completely degraded, but it was such a shocking event that I can't forget the memory itself.
