Blake is desparate to get his parents to agree to go to the beach. If the tantrum didn't work, he would run away.
Slowly Blake opens his bed room window. Could he open it without his parents hearing? Half way up the window always sticks. To cover the sound of the window Blakes screams again "This isn't fair!" He knows his parents will think he is still upset, but more important they will not hear the window.
Finally the window is open enough for Blake to get out. FREEDOM! His plans are to run away to his grandparents. He knows they will take him to the beach.
