Reading all of yours, I remember quite a few. I'm not sure which came first.
I remember being on a road trip, sleeping in the back of the station wagon (!), and waking up to a) being at a McDonalds, seeing the golden arches, and b) pulling into a Holiday Inn and being too sleepy to walk so carried inside.
My father was an avid newspaper reader, and I remember on one of these trips (often to NYC/Atlantic City, NJ areas, before casinos), he went out to get a newspaper and was held up with a knife and robbed, I remember his coming back to the hotel room all stressed out and blurting out the story, lol. (Not that that was funny but just chuckling thinking about it right now; he later used to tell the story frequently, too, and imitate the robbers: "Gimme the money, gimme the money!")
I remember many days being so happy when my father came home from work and sitting on his knee while he ate his dinner.
I, too, remember mindlessly sticking a key inside an electrical outlet and ZAP!
Yeah, I never did that again, either. Covers were a good invention!
I remember running on a commercial building's rooftop once and falling through some sort of dome, only to be caught by a board going across the bottom, looking down at the cement floor a couple of stories below. I was screaming and crying, and thankfully there was a man on a ladder painting the house next door who somehow heard me, and ran over and pulled me out. I remember lots about that building, which was a total hazard for a kid to be running around, as it was my father's business.
Lastly, I think probably one of my earliest memories was standing by our den and realizing my chest was going in and out and wondering why - my earliest understanding of the breathing process! Ha!
