Probably something like going to theme parks & family holidays. My long term memory is terrible to be honest but I do specifically remember enjoying those things from childhood. The first holiday I remember was going to France which was my first time on a plane.
Wow i think that is quite fun right ? But i have never been to another countries in my childhood. Of course not by plane or by something else. In my childhood flying in a plane is just like a dream. I used to make a paper plane and enjoy the game with my friends. But that is also a quite fun. By the way you are lucky. I think, you have enjoyed a lot in france? It is one of my dream to go to france one day.
