It does make some sense: if I have some apples, and I ask a child to count them, they'll address each one starting with the number 1, not the number 0.
Yes, indeed. But when indexing to an element in an array you aren't measuring from a zero (well, in memory you are, but not conceptually). You're conceptually pointing at an apple.
I think maybe it's just hard to unlearn the offset mentality. Of course you can convert a direct index mentality to an offset mentality, but I don't think anyone is pointing at the first item in a row of items and thinking "that's a zero offset from the start of the number of items". They're thinking, "That's item number 1".
