You're going to need nice weather for this writing adventure so I hope Mother Nature cooperates. Remember when you were a kid and you used to lie in the grass and find shapes in the clouds? Well, that's what I want you to do. Study those clouds until you've got three inspiring things (I found a fire truck, a dachshund and an ice cream cone) and then write a short story with each of the items in it.
(If you are the kind of person who never stopped lying in the grass and looking for shapes in the clouds even though you, supposedly, grew up long ago then we are kindred spirits.)
