I've turned the heel on my first sock. Forget about wondering what the purpose of life is. That is nothing compared to the magic that is turning the heel. It blows my mind that someone came up with a sock pattern in the first place.
Whoever did so was a really smart lady. I assume is was a woman, anyhow.
You are looking at the sock from the underside. That triangle shape is where the heel will fit.
The foot is not the most straightforward of body parts. You want a blanket? Knit a rectangle, and there you go! Warm. How about a sweater? Two rectangles plus tubey things with decreasing, boom! Warm. But a sock...
...that's an odd shape. What you start with (in this case) is a tube for the ankle. When you reach the heel, you have to knit straight down in a kind of wall called a heel flap. Then, you form a triangle for the heel. Once you get a certain number of rows, you pick up stitches and knit in the round, while simultaneously decreasing. Simple!
It doesn't sound simple, but when you're doing it, it is.
