When touching an electric wire, why do you become electrocuted when touching the ground, but not when you hang in it (or stand on it like a bird)?

Electricity flows along the easiest path to ground, so if you aren’t touching anything other than the wire, then you aren’t connecting it to ground. When you touch the ground and the wire, you become the bridge from the source to ground, the current flows through you, you get shocked.
