I would say no to this one.My dad bought me plane tiktecs to go to London by myself when I was 14, but the major difference here is that I stayed with my Aunt! I’d be really hesitant in relying on SIBLINGS (even if he were my own kid!) to care for my teenager. I’m sure he is a responsible person, and I wouldn’t be saying this with any intention to be mean to him or you guys but I just wouldn’t feel comfortable about it. And, as silly as it sounds, I would also say You’re 17 you only have one more year to go go when you’re 18! I would STILL prefer that you be older like 21 if you’re going to a place where you don’t know anyone, but hey you have your rights at 18 and I can’t stop you!Maybe I’m just a little over-protective after seeing Taken! But just remember your parents aren’t doing this to be mean they’re doing it because they think it’s the best thing for you. They think they’re protecting you. This isn’t a 3 day weekend trip to a place that’s 4 hours away. This is a trip to an entirely different country, where the rules are different, and the dangers may be increased! If something goes wrong, they can’t just hop in a car to rescue you! It sounds silly, like they’re exagerating on the things that can go wrong , but I think it’s very reasonable to think about these things.I remember being a teenager (I’m only 25!) and feeling like my parents were just being jerks when they denied me the opportunity for stuff like this. But believe me, when you get older, you’ll look back in the same way I am now. You’ll understand later!
