Meeting a Magical raindrop

The boy's name was Jake . He was nine years old. He was in his room staring outside. He heard big drops of rain splashing against the window and heard the sound of rumbling. Then he saw dark clouds and bolts of lightning, deserted streets and rain water washing the dirt away. All of a sudden he saw a magical raindrop which knocked on his window pane. The boy was startled. The boy opened the window to let the raindrop inside and then the raindrop jumped in and introduced itself.
