| Too old to act like a kid anymore, too young for anything "adultish":
"You shouldn't be watching cartoons anymore, you're fifteen years old now. It's time to grow up."
"No, you can't drive. You can't get a license at fifteen."
Sort of a state of limbo. It's the least remarkable age of the whole adolescent phase. No new privileges, no raised status, just the same double-standard. At least beyond sixteen, there's the possibility of being considered mature. No such luck here. Oh well, at least it's divisible by five. |
