Convincing my parents....?

I think that if you really want to go and can prove your responsible then you shouldn't have a problem but in case you feel that you need help on this i would list all the Responsiable things i had done in the past if i was you also you need to know how to keep yourself safe if you do go like bring a phone fully charged with credit and you could make a deal with your parents like having them take you up and back they would feel more comfortableble this depends if they drive a car also a thing that would help you in yofavourvor would be getting your friends parents numbers so that emergencyncy they can phone them to see where you are also you could i will be back such a time sorry to sound old and everything but keep yourself safe and just use all responsibleble things you had done in the past to convince them but be careful don't ask them about it too much give them sum time to think :)
