My earliest memory goes back to when I was about 5 years old. I was wandering my home and came upon an unfinished room. The room was under construction, so I could still see all the debris and mess as a result of the building process. In fact, at that time, the walls werent up yet, so I could also see the beams that would hold up that room together once it was finished. A few years later, the finished room became my room.
The fact that there was construction going on in my home as well as that the construction was for my current room at home was probably more than enough to make that scene memorable to me. I feel like I was more curious on the physical side of things back then. My present self hasnt lost that curiosity albeit its in a different area (more on the intellectual side).
I have been in a similar situation, when my house was under construction. I was around the same age and remember not being able to be in certain parts of my house, the noise of the construction early in the morning and all of the debris on the ground and in the air
