I was 3 or 4 years old, and I went with my parents to Florida on vacation. We stayed outside this beach with really fine grained sand. For some reason, the sand reminded me of sugar, and I kept calling it "sugar sand". I think at the time I thought it was some kind of brilliant discovery of association. Although this single memory gives limited information about who I was at the time, I would say my identity is quite different now from then. Definitely no complete continuity.
