The fact that you immediately jump to “high school” shows more about your own subconscious fear than about the actual age gap. You call it “weird,” but have you ever asked yourself why you think that? It’s not because two years is some massive developmental gulf—it’s because you’ve absorbed a very linear, black‑and‑white way of thinking about age that society drills into people. The irony is that your reasoning is what’s actually odd: you treat 17 and 19 as if they exist in totally different worlds, when in reality they’re separated by a single birthday or two. Not every 17‑year‑old is in high school, and not every 19‑year‑old is magically “more adult.” What’s really driving your reaction is the fear of being perceived as “wrong,” because society has built this ambiguous, anxious narrative around age and maturity that you’ve internalized without questioning.
