We may choose to trust or distrust certain ideas that can't be proved objectively, like "human nature is good", "love never ends" or "friends are forever". How we choose rely on our own experiences. If we keep coming across nice people, we would believe in the goodness of human nature. If we are surrounded by people who show unreserved love for others down to their last breath, we would believe in everlasting love. The idea of "forever" also falls into the same category. Just like "human nature is good", "love never ends" and "friends are forever", it is an idea we would gladly choose to believe in.

We would rather believe in the goodness of human nature and the existence of forever.

If we have been let down before, we would still keep trying. Even in the face of more failures, we would probably not give up easily because of our belief in the existence of forever. It is this wishful thinking that keeps us going.

However, there will inevitably come a time when we are too disappointed to go on believing. By that time, we will no longer be able to keep our faith no matter how willing we are.

"Almost believing it will last forever" —that point is just narrowly missed after we have held out all this time. If not for such a narrow miss, we would be able to hold on to our innocence, our innocent belief that it will last forever.

"Almost believing it will last forever"—just as it will never be possible for a child to stop growing up. No matter how hard he tries to stay young, he will grow up, and will one day get so old that he would almost forget he was once a child.
