In my opinion, if I were in a situation like that, I would probably get it. If you choose on getting it, you should most likely tell your parents and say that you are going to be responsible with it and you take proper safety precautions. When I first got into Airsoft, my parents were against it. (Mostly my Mum but still.) But I convinced them by saying I will responsible with them and will atleast try to take every safety precaution I can.
But don't only make your decision on my opinion, since mine can be biased at times and your parents might be different to this than mine did.
Best of luck,
