Need persuasive help! need you to answer this question....!!?

I am trying to get my parents to let me be able to hangout with guys (as friends). i have a good argument on why i should, the only thing i cant think of is why i should be able to hangout with them alone. im 15 and i know my parents trust me! the question i think theyll ask is why i need to hangout with guys alone as opposed to hanging out with guys but with girls(friends) as well. so what could my answer be for the question "why should i be able to hangout with a guy alone?" ....... ps. please only say an answer if its going to help with my question, thanks :)
