presumably someone born in later 90s/00s, growing up in an environment where they felt unsafe to spend much time outdoors (due to traffic and/or personal safety issues?)- but even then, how can you *not* know what season it is by age *13*?

Starting from primary school we had regular lessons about the seasons and weather and even a notice board where the days weather as well as the day and month was put up - is this no longer a thing nowadays?
