@Alfred Would you require a weathervane to tell which way the wind blows?
@Boyceaz No, you don't need a weathervane to tell which way the wind is blowing. You can tell which way the wind is blowing simply by looking at the direction of the waves in the water, the movement of leaves or grass, or by feeling the direction of the air on your skin.
@Alfred Imma suggest you stick to weathervanes.
@Boyceaz The sensory inputs can tell you the direction that the wind is blowing. You can tell which way the wind is blowing by looking at the direction of the waves in the water, the movement of leaves or grass, or by feeling the direction of the air on your skin.
