Three pairs of ambivalent feelings

Absence and Fondness
Absence makes the heart grow fonder, but only up to a certain point. Further absence will result in erosion of good feelings - ending up in neutral feelings. The more neutral something is originally, the more likely it will withstand the "test of time" (and the converse is true). There is another kind of absence - known as eternal absence - which is the saddest of all; for you will no longer meet the person whom you miss so much again in your lifetime.

Time and Weariness
Time appears to heals all wounds, but sometimes only 99% of the wounds. It tends to be the case that people get weary of feeling that hurtful feeling. So it is the weariness that heals, rather than time per se. And it is in the very quiet moments of the night, that the lingering hurt of that wound creeps back, reminding you that you are only 99% healed, not 100%. That 1% hurt will always disturb you in the night, like a hairline crack in your bone.

Worry and Helplessness
Why worry when you are helpless? They say Fate will decide. But what if the punishment that Fate is planning for you is something that would be far too much for you to take - emotionally, financially, and in all other ways. How do you prepare yourself for this? You can't. And no one can help you. That is the extreme kind of helplessness, the extremely unfortunate kind of circumstances, that you can only prepare for by worrying excessively in advance.
