15 is way too young for alcohol.
I agree with arguments saying we should not make alcohol seem exciting / exclusive and should introduce teens to it gradually, but that really applies to 17 yr olds, not 15 yr olds.
Im sure most 17 yr olds try to get into a pub while a little under age, but 15 is still very much a child, even if they dont think so.
I remember going on a day visit to a university from high school, when we were picking courses etc. I had recently turned 17.
The students touring us around took us into one of the union bars afterwards and - despite us being in school uniform - asked what we wanted.
Several people ordered alcoholic drinks but I was quite naive (had never drunk alcohol before) and didn't even to know what to ask for - and I wouldnt have liked it, even if I did.
So I just panicked and just said I didnt feel well to get out of having something to drink. 😂 It was really obvious and cringe worthy and then I got slaughtered from school friends for pretending to be ill. 😩
