I will start this by answering another related question… 😉
What does it mean when somebody is an adult?
In many countries it’s when you can drink, or watch pr0n, or do some things… Basically a child cannot do some things until they are considered an adult… They regulate it by age, 16, 18, 21 … depending on the “thing” and the country.
In Qatari culture, it comes directly from Islam: it’s not what you are allowed to do, being an adult is bearing more responsibilities, a child isn’t responsible for what they do, if they don’t pray, don’t fast, lie, cheat, god wouldn’t punish them (the responsibility of the parents would be to teach them to do the right thing)… When one reaches puberty they are adult, they are responsible for everything they do or don’t do: prayer, fasting, telling the truth, marriage/establishing a family, hajj … it’s endless.
Well, it isn’t by age, puberty is the main thing.
It’s much simpler than boys: the first period is the defining moment, she’s immediately adult… She’s not a girl anymore, she’s a woman.
We have to notice multiple factors: morning erections, they start looking at women differently… Hey, you’re a man!
In our culture, we don’t leave our parents’ house until we really have to, we don’t leave them when we’re a specific age…
I have 3 “adult” children, two girls (currently 17 and 14) became adults when they were around 10, my 11-year old son is a man… Their grandmothers got married at ages 13 and 15, they both had their first child in the first year (My mother was 16 when I was born).
