You can't. Your have to accept that you most likely can't change your parents opinion. If they trust you, you will be fine.
it matters how old are you
Prove to them that you're mature enough for a relationship.
You could convince them that you are responsible enough.. I don't really know it depends on the parents.
If you are not at least twenty years old, you will not be able to convince them because they were young once and they know you have to be a certain age before you can really be able to tell the difference between love and infatuation. If you have to convince your parents, you are not mature enough. When the time comes, you will only have to convince yourself.
You show them that you are responsible enough to take care of your self while you are out with a friend.
Try showing them how responsible you are by doing everything they tell you to do, because the most likely reason they are not getting you one is that they don't think you're responsible enough. Hope this helped :)))
you let them get to know him and take your time,Ask your boyfriend to come visit your house and show your parents how good and responsible enough to take care of you.Or, do the opposite.Show your parents how you can be responsible enough to have a boyfriend,parents usually are afraid you might eventually be getting to close with your boyfriend that then you end up by being obsessed with him.
You prove to them that you are mature enough to handle the content.
First sit down and explain to them why you want a kitten and that you think you are responsible enough to have one! Then do chores around the house showing you are responsible! And offer to earn money and pay for it's first bag of food!
You can be younger then 11 if you are responsible enough. But it is the parents final decision if you are responsible and old enough.
shouldn't have to, you're legally allowed to get one without parental consent which means in the eyes of the law you are mature/responsible enough to make the desicion for yourself :)
Clean your house. That's the easiest way. After that, just keep helping out. Just think of the the olden times.... those really really good children.
