At secondary school after years and years

Dear
Have you been at your secondary school after several years?
Have you met your professors since then?
I was finished with my studies at the secondary school about seven years ago.
I attended a school for technicians, you develop some technical skills in a particular field,
in my case I studied mainly electronics for telecommunication systems.
It means that mostly, during my last years, I focused on subjects like telecommunications, electronics, electrical systems and so on. It was my first time that I dealt with those topics.
At the end of my studies I also was a lecture in that school. Yes you read correctly.
For teaching to some courses you are not supposed to hold a master degree. Actually there are two kinds of professors, one of them is a "support teacher" who works during the lab sessions.
I was one of them :). It was fantastic, so young and already on the other side of the desk :)
My professors were my colleagues, some friends of mine were my students... so funny!
Well, after this experience that lasted some months (it wasn't a full time position) I have never
been there. Last week I decided to go there and get back in contact with my old teachers, longing to drive me?
I do not know it.
However a lot of my previous teachers were very proud of me, my achievements and my next adventure. One of them (that I've always considered to be a good and thorough teacher) enjoyed my choice.
He also wants to keep in touch and immediately involved me in a scholar competition as judge...
It is something that went beyond my expectation, they were really welcoming and nice.
Now that the "channel is open" as my teacher and me say :) we want to do more for the future. If I have time I want to submit them some ideas and to become the man in the middle between them and the university... many ideas in my mind... I love this :)
Now again, have you met your old teachers ? if so what was your feeling ? I'm prying to know ...
