I understand that. It gets harder. Eventually you run into people from high school who clearly never missed you in the sentimentally sloppy way that you have missed them all these years. Because they missed you not at all.
No I definitely dont miss that nazi kid from elementary and middle school.
Why did we end up in the same class?

Nor do I miss the bullies from middle school.
But my memory just likes keeping these files stacked up somewhere.
Now that I remember, I cant forget the teacher who hit me with the wooden stick

(this was in Pakistan lol)
I don't forget people, but I'm too used to separation to miss people. I usually miss someone for a while then my feelings evaporate.
Same. I feel it's better to move on.
