hey, (sentence)

Sometimes in English we use "hey" like this:

The meaning of this is something like "I disagree with you, but I can't do anything about it." Here is another example:

Hey, you're an adult now. If you want to spend all your money on useless junk, I can't stop you. But don't come asking me for money when you run out.
