Goodbye, easier said than done

I have no idea how to say goodbye. I know its a compound word, that has been around in every language since the beginning of time, yet I have no idea how to communicate this idea. In the past, I pull away from everyone. Fights that would never occur otherwise, would tear friendships/relationships apart. I don't want to do that. I hope that doesn't always happen.
Will I ever see these people again? It's hard to say. This chapter doesn't feel like its over. Maybe chapters can be revisited? Maybe, this was only an interlude. Whatever the case maybe, how do you say goodbye?

Farther along we'll know all about it

No one is beyond their past.

No one can escape memories which has been fully rooted in the past.

Today, I reverted. I went back to my old way of approaching an idea. I debated it. Debate has nothing intrinsically wrong with it. Many use this as a tool for good. In fact, part of my learning style is to put somethings against the stark opposite. However, this is only good in certain context.

If you were raised like I was, this is an acceptable practice. Everyone knows the rules and tries not to take things too personally. However, most people were not raised like this.

Contextual analysis seems to be a point that needs further observation in life. While something is appropriate in one setting, it might be the antithesis at other points.

How are you able to tell?

logically

Change is the only constant.
Some changes are better.
All constants are better.

This would be an invalid syllogism. Logically, not all changes are constant. Since only some changes are better; this does not necessitate that the constant is better. It COULD be, but it also might NOT be.

Logic sucks.

This is because logic most purest form is a completely abstract concept. Abstract concepts can only exist in the philosophical realm. The concepts cannot enter into the physical realm without putting on the heavy concrete clothes which adds or possibly removes aspects from the original concept. Thus, logic can not exist in the physical realm.
Unfortunately, while the above syllogism is invalid logically; it is reality. Not saying that every that is constant is a better alternative, but everything that is constant is something which is better than nothing. Even if the nothing, seemed better than the something. However, bad you wanted the nothing to be something; sometimes it turns out to be nothing but at the same time something.

P.S. I've missed posting... but not all posting is missing... ergo I equals missing?
