@theressomanytinafeysicouldbe Well, clouds banging together is not that far off the reason for thunder: expanding hot air from the lightning pushing the colder air away.
I remember when I didn't make the connection between somebody holding a camera, and photos in an album; of course, this was long before digital cameras, and it could be weeks between a photo being taken, and actually seeing it. I thought they just "happened". It became clearer when I saw someone use a Polaroid camera, and then my mum explained photos to me, and taking film to be developed.
Marriage: I thought it just "happened", like being born. I didn't understand the whole process of people coming together until I was about twelve: dating, engagement, wedding; and even then, I wondered why literature made such a massive deal of people falling in love, and I was totally baffled by the whole boyfriend and girlfriend thing. I never saw any adults in my life get married: all of my parents' friends were already married, so I never really saw the process for myself.
Not one that followed me into adulthood, but confused me for a day (I must have been 5). I was told at the start of a party that we would play "pin the tail". I asked what the game was, and was told "the winner is the person who pins the tail closest to the right spot". I remember thinking how easy this must be. I was asked if I would like to go first, and it was a shock when I was blindfolded: nothing had been said about that! It wasn't fair that I couldn't see to pin my tail.
😭
@DigitalGoat I know what you mean about the game Sleeping Tigers being played to give the adults a break. I'm sure that "Keeper of the Keys" was played at my youth group for a similar reason: one person would sneak up and try to steal keys from the blindfolded keeper, who pointed at any sound they heard. Adults loved this game because it was very quiet.
When I went on an overnight trip with a youth group, aged six, my dad came too, as a helper. But we left after only one night. I thought this was because I wasn't enjoying the trip much, which was true. But many years later, my dad explained that some of the teenage helpers were having sex in the dormitories during the day, and some of the children knew this.
