In a room with a single window, Zephyra is standing with her back to the window, and a breeze is flowing into the room. She notices her friend Elowen's hair is blowing forward. Without turning around, what can Zephyra infer about the direction of the wind outside, and what effect is it having on the curtains of the window? Respond very briefly.
Zephyra can infer that the wind outside is blowing into the room from the window. Since Elowen's hair is blowing forward and Zephyra is standing between Elowen and the window, the wind must be coming from behind Zephyra, moving over her head, and then reaching Elowen. Regarding the curtains, Zephyra can infer that they are being pushed inward by the wind. If the curtains were light enough, they would likely be billowing into the room, away from the window. If the curtains are heavier, they may not billow much but would still move in reaction to the breeze, depending on their weight and the strength of the wind.
