How do you use question tags to seek permission?

To use question tags to seek permission, you would add a tag question to the end of a sentence to confirm or seek agreement. For example, if you want to ask for permission to do something, you would make a statement and then add a tag question at the end, such as "You don't mind if I borrow your car, do you?" or "I can use your computer, can't I?" The tag question seeks confirmation or agreement from the listener.
