messages hidden in the wind

It was a very windy day, the envelope was shaking violently in her hands. The
wind was messing with her red hair, which looked like fire in contrast with the
grey clouds. Beneath the bridge where she was standing, there was a very deep cliff that divided the city in two, and all the way down was a river that lead to the ocean, just a few miles ahead.

The envelope was finally let go and it flew through the air. This was the fifth time that she had felt the need to fold a blank piece of paper and put it into an envelope. She carried it with her until she felt it was pointless and abandoned it anywhere. A few days later she found out that the "letters" did have a destination, and than when they arrived they all had messages in them with what it seemed her handwriting.

They were messages hidden in the wind, too weak to be heard but too important
to get lost.

She doesn't know how that happens or why it happens. It is her handwriting but she is 100% sure she never wrote anything herself, and later she starts to hear voices in the wind, whispers.
