Imagine you are of your friend's birthday party. your Friend is asking you to stay there. You have to ask your Parents for permission. Have a conversation you and your parents. ​

It depends on their  mood and the day. If they're in a good mood and it's the weekend I would start the conservation by asking if they have any plans, then I'd say positive points of it. Such as: "I study a lot and I think I deserve a little break to destress".. "It's been a while since I've seen my friends don't you think I should go for a bit?"

I don't know but like you want to persuade them in the best way as possible, also include that you are trying to be more responsible and maybe add that you're mainly indoors and you want to have some fun.

it u understand what he thought at the time and let u know more about him then what third person would of known probably. hope this : )
