A similar question as the European vs American approach to handling alcohol. In Europe (vast oversimplification incoming, big continent with lots of cultures and jurisdictions) it's normal to drink beer the first time by 14, in the presence of your parents, and are typically able to buy it freely at around 16. In the US (oversimplification incoming) you typically have your first experience with alcohol in secret, or binge-drinking once you are 21 and free from your parents. The European version typically results in more alcohol being consumed, but in healthier habits
One crux is that this only works if the parents are actually using alcohol/social media in a healthy way. A heroin addict can't teach their children how to responsibly use heroin
You did disclaim about this, but my understanding is that most European countries no longer allow you to buy alcohol before you’re 18 (but with some major exceptions like Germany and Belgium). Culturally, you are however quite spot on.
Those were the literal words we used!
