Well, at least he knew it what a bottom bracket and seat tube was.

I met a guy on a bike that cost more than my entire build history combined, and he didn't know his bike's size. He bought it from a shop he trusts, rides it, and they service it. He can't tell you what tires are on the bike, the type of bar wrap, chain lube, or cassette cog range. He truly doesn't care, loves the bike, and rides it.
