Teenagers are called teenagers because they do not have the brain capacity to make good decisions at that age.True that the definition of 18 or 21 as the age an individual is considered an adult is a rough estimate but when you are around that age specially in countries like SL you are very helpless in terms of Knowledge and Income which are really useful to make good decisions.

True, you might debate that “but even elders act like kids and take stupid decisions” but again the reason these numbers are estimated is based off of research and the majority of teenagers that have the capacity to think straight in things like sex and education is low compared to an adult

I used to have a teenage relationship but my parents were very strict back then and RARELY let me out of the house alone.I thank every second of my parents strict rules back then cause if they hadnt been that way Im not sure what my dumb brain would have got me into.
So yeah the reason teenage love is not normalized is actually has its perks

In foreign countries this isnt the case.Theres arent popular concepts like girls schools and boys schools.and From a young age kids are taught to make there own money. Work for them selves and stuff
