I posted something similar to this a while ago in the "general" section, but I didn't get much of an answer at all. I think it's a rather relevant topic, and should at least be thought about.
Anyways.
A few weeks ago, I was in my car driving to get some things from the grocery, and came to a stoplight with a school bus to the left of me (I live in the US, so I was in the front left, as opposed to right seat) so that I could see directly up the stairs to where the bench seats are, coming almost even with the front of the bus itself. In the part of my town where I live, the high school I attended (I'm in college now) was close enough so that I had to either walk, or ask my mother to drive me there every morning, removing the need to ride a bus.
This means that the only time I rode the bus to school (relevant to the topic) was in middle school. which was by no means pleasant for me.
Anyways, to the main point: when I looked over up into the school bus, memories of being bullied, pushed around, etc.. came rushing back into my head. Are these events things I had just forgotten? Or were they suppressed? What's the actual difference between the two, when it comes to unpleasant memories?
