The evolution of what my dad did:
I thought my dad was a construction worker because he sometimes took a hard hat to work with him. Later, he corrected me and told me he was an engineer, so then I thought he drove trains. Turns out he was "just" a mechanical engineer, and for some reason, I thought that meant you had a "uniform" that consisted of short sleeve dress shirts with ties.
