Me?
I'm 19.
Tell me, oh wise and mighty N/A year old, when is it you're old enough to feel love?
Love is no more than a chemical reaction in the brain, you can feel it at any age.
Now, what you're referencing are the things that come with love, the coping, the understand, the true emotional complexity that you never truly understand but you're forced to work through. That's what I'm assuming you're talking about. That's more prevalent.
But love? A basic human emotion? Yeah, anyone can feel that, you ass.
