Side by side

There was once a boy who likes to walk on his own. One day he happens to look back and notices a boy of the same age following him. He looks strangely familiar to the boy, however the boy cant seem to recall where he has seen him before. The boy ignores the one following him and carries on walking by himself. After awhile he looks back again and the boy following him is still there.

"Who are you?" he asked the one following him.

"You don't know?" asked the other boy in surprise.

"No. I don't," he replied frowning slightly.

"You just forgot." said the other boy smiling slightly.

With that both boys carried on walking, one following the other. For years this carried on. The boy walking on his own with the other boy following without saying a word to each other. one knowing the other is always following him, the other knowing that one will continue walking alone. Then comes the time when both turns 21. The boy always walking alone finally stops walking and turns around to face the person always following him.

"Why?" the boy asks simply.

"So that 1 day you will remember," the other one replies.

"When will that be?" the boy asks. The other one shrugs.

"What will happen if i remember?" the boy asks. The other one gives him a smile and looks up at the sky.

"That will be the day we start walking together."
