My grandfather would take me to museums, and we'd go by bus, as he never owned a car. We'd get on the bus, and I noticed that it wouldn't go anywhere until he put coins in. So I figured that it ran on coins, but I couldn't figure out how it would burn metal for power.

Yea, we failed.
I thought of something like that, too. Then my dad explained the law of conservation of energy, and the impact of friction. I probably knew about that stuff years before it was ever addressed in school.
When my training wheels were removed from my bicycle, I absolutely refused to ride it, for about two weeks. I just didn't see any way that something standing on only two wheels could possibly balance. I wasn't fully versed in gyroscopic principles at that time.

I did eventually find that I could even balance the bicycle reasonably well while standing still.

Or that police were all fine, upstanding citizens, or that government officials were all honest people, there purely to serve and protect the public interest. Sadly, it wasn't until high school when I started learning otherwise. Then I slowly began to make a realization I'd suspected for awhile: reality really kind of sucks.
