Default Electricity



I have a somewhat practical question about electricity - namely household
electricity. I have read, and finally understand a bit about electricity.
From what I have read, The hot wire carries the energy; the neutral wire is
a ground, and the ground wire is there in place of a short; to safely
dissipate the hot current to the ground.

What I don't understand is, in most places I've read, and from my
understanding, what actually happens with electricity is electrons want to
flow from the negative terminal, through the load, to the positive terminal.

So, is the hot wire in a house the negative terminal, and the neutral wire
the positive terminal? It is unclear to me. With this, do electrons want to
flow from the green ground to the hot wire? Or is all this vice versa. If
so, what is going on with the hot wire? If it is the positive terminal,
does the electric power wires delivering the hot wire simply try to pull
electrons to it, creating the current through the load?
