Well, raindrops mean some wild plants (and flowers sometimes) growing, on their own and already planted trees getting green again and when the rain stops, well, those wild plants start to shed of their leaves and probably die (that "die" was actually hard to type, dunno why. Was looking for a better word but could find. Lol!
Okay, you may see yellow leaves falling here and there but that just isn't it... Lol! Too boring...
