Sometimes, you have something to say/do for someone and you feel hesitant for an eternity because you know based on past experience and previous knowledge that there’s a layer to that action which could hurt them; something you don’t want to do.

So after much thinking and worrying whether to take an action or let go, you take it and prepare to talk it out and explain if the hurt happen, wishing that it won’t.

But then it turns out that someone has changed so you don’t have an impact anymore, or worse, what you remember from their words, their past actions and reactions are long forgotten by them and you were being thoughtful for things that were erased or replaced.
