For most of my school career I was bullied. The first 6 years were the worst. I was a bit of a brainiac, and also a bit of a geek.
But after these years, and a switch to secondary school things changed. I met more than one person with an actual brain. Of course there was a lot of banter, but I could almost always riposte well, without it being negativistic. Those were really enjoyable times.
I was always an outsider, and I liked it that way, especially as people knew that was normal for me. Still they made an effort to get me involved a bit more
I did not start smoking, weed or whatever on school. Still I don't smoke a thing. The only bad habit I started on secondary school was laziness. But that was, because the education was not challenging at all.
