To me, kids in the street doesn't just mean putting life before responsibility. It's the rush of adrenaline you get when you take advantage of every moment without considering your responsibilities.
To me, being a kid in a street is ditching 6th period and going to Starbucks with your friend. It's finally cutting out time to hang with your best friend whom you haven't seen in a year because both of you have been really busy. It's sneaking out of tutoring (and almost getting caught) and racing at 80 mph(on local and residential streets) to get Chipotle with 3 of your friends and laughing your head off when one of them screams, "I'm gonna die!" It is listening to music (AAR) and relaxing instead of studying for SAT II physics (every Asian parent's worst nightmare). To me, kids in the street is forgetting about everything in your life when you go horseback riding and racing through the trail not caring about getting caught.
To me, kids in the street is the pure excitement and nervousness of doing those things and wishing those moments would never end.
