Short story about leaves

Once I heard a story about two leaves that were friends. They were born at the same season and would have the same time of life. They were conected by the same twig, almost twins. One day, when winter was almost there and they knew that their time of life woudn't be much after the first snowflake, a couple sat under the tree and begun to talk. The girl was saying something about farewells and the boy was almost crying. Then the two leaves faced one another and started to pay attention in their voices. The boy said: "I'm pretty sure that this is just an end of a season, some isolated moment in our lives. Maybe I'm too optimistic, but what we had, what we shared, can not be forgoten. Even what dies go to somewhere, somehow is transformed in some kind of a new energy", at this point the two leaves understood what they were talking about. That was a goodbye. None of them would die, but "both" as "one" would not exist anymore. They thought about everything they saw from that point of view in the tree and realized that they wouldn't really die... but being transformed in something else. The couple kissed each other and the girl up her hand to take one piece of the tree... Then she took the two leaves. She gave one to the boy and kept one to her, saying: "These two leaves will die, as everything does, but the meaning will remains, just like us". The two leaves couldn't say goodbye properly, they still didn't know if that would be a good or bad way of pass their last days as leaves on earth, but what happens is done and that's all. The only really sad part was: will they be alone till the end? They would found out soon. About the couple... well, they forgot the leaves, as they forgot each other.
