As a small kid i once rode my kickscooter in a similar parked car, cause to be honest I wasn’t looking and also wasn’t expecting a car to pretrude like one meter into the sidewalk. While I was definitly careless (and also like 5) you should expect accidents happening when you leave stuff in places they don’t belong.

I vaguelly remember around this time some low end computers were shipped with FreeDOS instead of Windows, in order to save on licencing fees. AFAIK this was the case because legislation in some european countries restricted the sale of new computers to ones which had an OS preinstalled.

Maybe XP was installed after the purchases however a partition with FreeDOS/whatever remained as the default boot option. Hence your parents had to select the other boot option (Windows XP) manually. Granted you could change your primary boot partition permanently, but maybe your parents didn’t know this.
