When I was five, my father made a promise he never intended to keep. He had returned from a long trip, with presents. I got a fossilized shark tooth, and spent the next month asking about fossils.
At some point, my father made the mistake of describing a massive fossil bed somewhere in Germany. I begged him to take me. There were good reasons that could never happen. Dad knew nothing about fossils; Germany was far away; I was five. But I would not be deterred.
