I love you, Charlie

He finished reading, and as he was about to put down the pages on the bed, the woman opened the bedroom door.
- What's that? - She asked quietly, afraid, like if she didn't want to know the answer.
- They're letters... from Charlie.
The woman turned around and left, her hand over her face, closing the door behind her. He stayed in the room. He carefully aligned all the letters and put them in the side table. He took a long time to make the letters look perfectly aligned, between the lamp and the alarm clock. He then let himself fall gently over the mattress, and his heavy head sink into the pillow. On top of that bed, you would see a remaining piece of paper with the dog care. He pulled his legs up as he stared into the void.
He set the alarm clock and put it down on the table. Now he had all the time in the world.
For what?
