I have several of these, but not really strangely enough, none of them were with my family unlike a lot of people. Most of them are actually with myself or other kids... it's strange. And they all took place in the evening or at night.
The first one was in 2006, I was probably 6.5 years old. I was living in Martinique at the time. It's incredibly small, I think you can go across it in an hour and half probably. It'd probably seem even smaller to me now that I'm an adult. I was sitting in my mum's car (a Peugeot 306) and the radio was on. We were either going somewhere or returning home, I don't really recall, but it was starting to get late and the sun was setting. There was some sort of commercial zone with malls and stuff, including a big rug store that had burned, and Unfaithful by Rihanna was playing. 6 year old me liked this song and I just remember listening to it while the sky was a beautiful pink. I was feeling so at peace. We only lived six months in Martinique, but I have overall good memories there. The other kids were nice, I played with the kids of my mum's friend, the only downside was the heat and the potentially dengue-infected skeeters.
The second one was in 2008, I believe, so I was about 8-9. I was attending some sort of event at my father's regiment. I don't remember precisely what it was, but it was in summer, and we all went to the mess. Behind the building was a garden of sorts with a little bridge on some sort of mini artificial river. I was playing with other kids the whole evening. I don't even remember their names or faces but I still remember fondly that I was having fun. I took a picture of the little bridge with my dad's phone, but it got lost (apparently it was blurry too, so...). The night fell and me and the other kids stayed outside. We watched the stars. The adults were all inside while we were outside. Again, it was so peaceful. But damn, that little bridge. This regiment has since been dismantled and now I believe the buildings are now police quarters or something like that. I don't think I'll ever see that little bridge again, but... I still have it in my mind.
The third was in early 2018, I had just turned 18. I was living in a roach infested dorm room at the time and I would also go on night walks, despite it being dangerous for a long young woman. I remember I wasn't able to sleep and had a bad stomach ache. It wasn't going away, so at some point I dressed back up and went outside. I thought, better throw up outside in case I get nauseous or something. It was around 4 AM and it felt like a dream. Everything visually seemed surreal, I felt sort of "floaty", no one was there, except maybe a handful of guys, but I was staying in the shadows so no one would notice me. I walked around for an hour or so until I went to a park next to the Garonne river, right next to the bridge called Pont Neuf. I discreetly went to lay on a bench that was directly next to the water and facing the bridge, which was really beautifully lit. Had a cigarette. My stomach pain eased and I tried to rest a bit. At some point, I saw the first bus of the morning setting off. I went home around 6 am, crashed into bed still dressed and woke up around 1pm. Of course, I was told I was out of my mind for walking around at night, but I loved it. And I don't care, I'll go on more night walks in the future. I just won't tell anyone.
