Letters Going Nowhere

He never thought of what would happen after they were sent. He didn't think about who'd read them. Blake stared at the letter in his hands. He turned over the letter and and broke the seal.

Blake isn't a typical teenager, who hangs out with his friends or listens to music. He isn't the smartest guy ever. His mother died in a car accident 3 years ago that took his 9-year-old sister's ability to walk. He lives with his father who's been a drunk since the accident. Blake isn't enjoying life, and has thought of taking it multiple times. He hasn't talked to the friends he had before the accident for 2 years. Blake just keeps to himself. But one day, he sends a letter to a random address about his thoughts, and feelings, and emotions. Then one day he gets a letter back.
