Hullo @susier,
just for what it is worth I concur with earlier:
* your message is quite appropriate
* first flight had better not be too long
And I would add the advice to go to the airfield well in time, and watch what goes on, so as to already get a feel for what is done, and how.
I also agree with the suggestion for the C42, or similar. It is an excellent craft for a beginner and quite affordable. It is a high winger with two seats side by side, you could call it a miniature C152. Be warned though that it is even more basic than a Cessna - but I think that should not deter a person who goes into engineering, probably at the contrary.
Good luck!
